I. Overview

Various embodiments of the present invention improve the field of predictive data analysis by decreasing the amount of data needed to be transmitted from client devices to predictive data analysis servers in order to perform cross-geographical predictive data analysis. For example, various embodiments of the present invention disclose techniques for reducing the amount of predictive input data needed for performing predictive data analysis by generating parts of the predictive input data using simulation. In an illustrative example, when performing zoonotic disease outbreak forecasting, a predictive data analysis server can utilize state-wide predictive input data (e.g., state-wide outbreak data, state-wide weather data, state-wide insurance claim filing data, and/or the like) to simulate district-wide predictive input data for districts within the state (e.g., district-wide outbreak data, district-wide weather data, district-wide insurance claim filing data, and/or the like). By reducing the amount of predictive input data needed for performing predictive data analysis, various embodiments of the present invention reduce the number of data transmissions from client devices to predictive data analysis servers needed in order to perform predictive data analysis, thus increasing network transmission efficiency of distributed predictive data analysis architectures.

Furthermore, reducing the number of data transmissions from client devices to predictive data analysis servers needed in order to perform predictive data analysis also decreases chances of data loss due to network hardware errors and/or network software errors, thus increasing reliability and effectiveness of distributed predictive data analysis architectures in addition to increasing network transmission efficiency of distributed predictive data analysis architectures. Moreover, various embodiments of the present invention introduce data forecasting techniques that have, in experimental observations by the inventors, outperformed various state-of-the-art data forecasting techniques, especially with regard to long-term trend forecasting and/or forecasting of rare but costly events such as zoonotic disease outbreaks. Accordingly, various embodiments of the present invention make important technical contributions to the field of predictive data analysis and to improving the efficiency and reliability of various existing predictive data analysis frameworks, including various existing distributed predictive data analysis frameworks.

IV. Exemplary System Operations

FIG. 4 is a flowchart diagram of an example process 400 for performing cross-geographical event prediction. Via the various steps/operations of the process 400, the predictive data analysis computing entity 106 can efficiently and effectively perform cross-geographical event predictions without requiring input data for hierarchically inferior geographic domains (e.g., districts within a state). In doing so, the process 400 can reduce the amount of input data transmission from client devices (e.g., external devices 102A-C) to predictive data analysis servers (e.g., the predictive data analysis system 101) required in order to enable the noted predictive data analysis servers to perform cross-geographical event prediction with greater network. Accordingly, the process 400 can enhance the network efficiency of remote predictive data analysis servers.

The process 400 begins at step/operation 401 when the predictive data analysis computing entity 106 determines forecasted superior domain event data for the hierarchically superior geographic domain at a forecasting period. In some embodiments, a geographic domain is a data object that describes one or more geographic regions (e.g., one or more continents, one or more countries, one or more provinces, one or more districts, one or more cities, one or more postal code areas, one or more neighborhoods, one or more streets, and/or the like). A hierarchically superior geographic domain may be any geographic domain that comprises one or more hierarchically inferior geographic domains. An example of a hierarchically superior geographic domain may be a state that includes one or more hierarchically inferior geographic domains such as one or more intra-state districts.

In some embodiments, forecasted superior domain event data is a data object that describes a predicted likelihood of occurrence and/or a predicted frequency of occurrence of a corresponding event type in a corresponding forecasting period (e.g., a future period as of the time of a forecast) for a corresponding hierarchically superior geographic domain. For example, particular forecasted superior domain event data may describe the predicted frequency of filing of medical claims related to a particular zoonotic disease in a corresponding state in a future period. In the noted example, the state is a hierarchically superior geographic domain associated with the noted exemplary forecasted superior domain event data, while filing of a medical claim related to a particular zoonotic disease (e.g., bird flu) is an event type associated with the noted exemplary forecasted superior domain event data.

In some embodiments, the forecasted superior domain event data is determined based at least in part on at least one of the following: (i) observed superior domain input data for the hierarchically superior geographic domain at an observation period, and (ii) observed superior domain event data for the hierarchically superior geographic domain at the observation period. The observed superior domain input data may be a data object that describes observed values of one or more data variables (e.g., one or more weather-describing variables, one or more disease-outbreak-frequency-describing variables, one or more claim-fling-frequency-describing variables, and/or the like) associated with a hierarchically superior geographic domain (e.g., a state) during an observation period (e.g., a past period as of the time of a forecast). For example, particular observed superior domain input data may describe the mean temperature of a corresponding state during each month of a multi-month observation period. As another example, particular observed superior domain input data may describe the aggregate number of flu patients in a corresponding state during each month of a multi-month observation period. As a further example, particular observed superior domain input data may describe the aggregate number of flu medical claims filed in a corresponding state during each month of a multi-month observation period.

The observed superior domain event data may be a data object that describes an observed likelihood of occurrence and/or an observed frequency of occurrence of a corresponding event type in a corresponding observation period (e.g., a past period as of the time of a forecast). For example, particular observed superior domain event data may describe the observed frequency of filing of medical claims related to a particular zoonotic disease in a corresponding state in the past n unit periods (e.g., months, weeks, quarters, days, and/or the like), where n may be a predefined and/or a trained hyperparameter of the predictive data analysis computing entity 106. In the noted example, the state is a hierarchically superior geographic domain associated with the noted exemplary observed superior domain event data, while filing of a medical claim related to a particular zoonotic disease (e.g., bird flu) is an event type associated with the noted exemplary observed superior domain event data.

Operational examples of forecasted superior domain event data 502, observed superior domain input data 503, and observed superior domain event data 501 are depicted in FIG. 5, which provides an operational example of a superior-domain event forecasting data object 500. As further depicted in the superior-domain event forecasting data object 500 of FIG. 5, the forecasted superior domain event data 502, the observed superior domain input data 503, and the observed superior domain event data 501 are associated with the hierarchically superior geographic domain 511 which describes the state of New York.

As further depicted in FIG. 5, the forecasted superior domain event data 502 is associated with a forecasting period 522, while the observed superior domain input data 503 and the observed superior domain event data 501 are associated with the observation period 521. The observation period 521 and the forecasting period 522 each include various unit time periods (e.g., months, weeks, quarters, days, and/or the like].

Moreover, as further depicted in FIG. 5, the superior-domain event forecasting data object 500 further includes simulated superior domain input data 504 associated with the hierarchically superior geographic domain 511 at the forecasting period 522. Various aspects of the simulated superior domain input data 504 are described in greater detail below, e.g., in relation to step/operation 602 of FIG. 6.

In some embodiments, step/operation 401 can be performed in accordance with the process depicted in FIG. 6, which is a flowchart diagram of an example process for determining forecasted superior domain event data for a particular superior geographic domain at a particular forecasting period. The process depicted in FIG. 6 begins at step/operation 601 when the predictive data analysis computing entity 106 determines preliminary superior domain event data for the hierarchically superior geographic domain at the forecasting period based at least in part on the observed superior domain input data for the hierarchically superior geographic domain at the observation period (e.g., the observed superior domain input data 503 in FIG. 5) and the observed superior domain event data for the hierarchically superior geographic domain at the observation period (e.g., the observed superior domain event data 501 in FIG. 5).

In some embodiments, to determine the preliminary superior domain event data for the hierarchically superior geographic domain, the predictive data analysis computing entity 106 utilizes one or more a preliminary machine learning framework comprising one or more inter-connected preliminary machine learning models trained to determine the preliminary superior domain event data based at least in part on the observed superior domain event data and the observed superior domain event data, where the one or more inter-connected preliminary machine learning models may be configured to decompose a predictive signal generated based at least in part on the observed superior domain event data to generate decomposed signals, process the observed superior domain event data to generate exogenous variables, and process the decomposed signals and the exogenous variables to generate preliminary superior domain event data. In some embodiments, the inter-connected preliminary machine learning models may include an ensemble learning model configured to aggregate predictive outputs of at least some of the noted inter-connected preliminary machine learning models in order to generate a unified predictive output for the preliminary machine learning framework.

In some embodiments, step/operation 601 may be performed in accordance with the process depicted in FIG. 7, which is a data flow diagram of an example process for determining the preliminary superior domain event data. The process depicted in FIG. 7 begins when a feature processing unit 701 of the predictive data analysis computing entity 106 retrieves event data 711 associated with a particular event type (e.g., a zoonotic disease outbreak frequency data) and a particular period of time (e.g., a first sub-period of the observation period) from the storage subsystem 108. The feature processing unit 701 then processes the retrieved event data 711 to generate a timeseries distribution 712 for the retrieved event data 711. In some embodiments, to generate the timeseries distribution 712 based at least in part on the retrieved event data 711, the feature processing unit 701 performs one or more univariate timeseries analyses on the event data 711. Examples of univariate timeseries analyses include autoregressive (AR) analyses, autoregressive moving average (ARMA) analyses, autoregressive integrated moving average (ARIMA) analyses, Holt's Winter's smoothing analyses, mean-absolute-percentage-error-based analyses, autoregressive conditional heteroscedasticity (ARCH) analyses, and generalized autoregressive conditional heteroscedasticity (GARCH) analyses.

In some embodiments, the event data 711 utilized by the feature processing unit 701 to generate the timeseries distribution 712 include a timeseries signal determined based at least in part on the observed superior domain event data. For example, the event data 711 may be determined based at least in part on data indicating a number of occurrences of a particular event (e.g., outbreaks of a particular disease) over a period of time in relation to a corresponding hierarchically superior geographic domain. In some embodiments, the event data 711 include timeseries event data. An operational example of timeseries event data 800 is depicted in FIG. 8. As depicted in the FIG. 8, the timeseries event data 800 includes a timeseries signal that comprises timeseries data describing incidences of flu virus in a corresponding state during a particular period. In some embodiments, the timeseries distribution 712 is a refined timeseries signal generated based at least in part on the raw timeseries signal of the event data 711, where the timeseries signal refinement may be performed using one or more univariate timeseries analyses.

The process depicted in FIG. 7 continues when an exogenous variable generation unit 702 of the predictive data analysis computing entity 106 retrieves input data 713 for the particular period of time and processes the retrieved input data 713 in order to generate exogenous variables 714. In some embodiments, input data 713 are determined based at least in part on at least one of the observed superior domain input data and the observed superior domain event data. For example, the input data 713 may describe at least one of the number of occurrences of a particular event in a corresponding hierarchically superior geographic domain over a period of time, observed weather patterns of the corresponding hierarchically superior geographic domain over a period of time, insurance claim filings of the corresponding hierarchically superior geographic domain over a period of time, and/or the like.

In some embodiments, the exogenous variables 714 include aggregate measurements for each defined subperiod of a particular time period associated with the input data 713. For example, the exogenous variables 714 may include, for each subperiod (e.g., month) of the particular period: (i) the raw number of occurrences of a particular event (e.g., outbreaks of a particular disease) during the subperiod; (ii) one or more seasonally-adjusted numbers of occurrences of a particular event during the subperiod (where each seasonally-adjusted number of occurrence may be associated with a particular seasonality measure, e.g., a three-month seasonality measure, a six-month seasonality measure, a twelve-month seasonality measure, and/or the like); (iii) a measure of trend and/or rate of change of occurrence of the event during the subperiod; (iv) raw maximum temperature measure and/or raw minimum temperature measure during the subperiod; (v) one or more lagged maximum temperature measures and/or lagged minimum temperature measures during the subperiod (where each lagged temperature measure may be associated with a lag interval, e.g., a lag interval of one, a lag interval of two, a lag interval of three, a lag interval of five, and/or the like); (vi) raw maximum humidity measure and/or raw minimum humidity measure during the subperiod; (vii) one or more lagged maximum humidity measures and/or lagged minimum humidity measures during the subperiod; (viii) raw maximum precipitation measure and/or raw minimum precipitation measure during the subperiod; (ix) one or more lagged maximum precipitation measures and/or lagged minimum precipitation measures during the subperiod; (x) a count of insurance claims for a particular set of medical claims associated with a particular event during the subperiod, where the claims have been filed in a corresponding state associated with the exogenous variables 714; (xi) a count of insurance claims for a particular set of medical claims associated with a particular event during the subperiod, where the claims have been filed in a state deemed to be a bordering state of the corresponding state associated with the exogenous variables 714; (xii) a count of insurance plans and/or insurance members associated with a particular set of medical claims associated with a particular event during the subperiod in a corresponding state associated with the exogenous variables 714; (xiii) a count of insurance plans and/or insurance members associated with the particular set of medical claims associated with a particular event during a subperiod in the states deemed to be bordering a corresponding state associated with the exogenous variables 714; and/or the like.

The process depicted in FIG. 7 continues when a decomposition unit 703 of the predictive data analysis computing entity 106 utilizes the timeseries distribution 712 to generate decomposed timeseries distributions 715. To do so, the decomposition unit 703 may perform empirical mode decomposition (EMD) on the timeseries distribution 712. The decomposed timeseries distributions 715 may include a first number of intrinsic mode functions (IMF) distributions and an error distribution. Performing EMDs, IMF distributions, and error distributions are described in greater detail below. While various embodiments of the present invention discuss decomposing the timeseries distribution 712 using EMD, a person of ordinary skill in the relevant technical field will recognize that other decomposition techniques may also be utilized.

EMD may decompose an input timeseries distribution into IMF distributions that satisfy two criteria: (i) for each IFM distribution, the difference between number of the extrema values (i.e., both maxima values and minima values) defined by the IMF distribution and the number of zero values (i.e., zero-crossings) defined by the IMF distribution cannot differ by more than one; and (ii) for each IMF distribution, the mean value of the upper envelop of the IMF distribution and the lower envelop of the IMF distribution cannot be zero at any point in the domain of the IMF distribution. The EMD may be performed in accordance with a fundamental part of a Hilbert-Huang transform (HHT) process and may be configured to decompose given timeseries signal data that are not set analytically and are instead determined by analyzed sequences only.

In some embodiments, performing EMD comprises generating IMF distributions in a recursive manner until no new IMF distribution satisfying the above criteria can be generated, and subsequently generating an error distribution based at least in part on the residue of the noted recursive IMF distribution generation process. In some embodiments, performing EMD comprises generating IMF distributions in a qualified recursive manner until either no new IMF distribution satisfying the above criteria can be generated or until a predefined maximum number of IMF distributions (e.g., a maximum number of four IMF distributions) have been generated. At each iteration of IMF distribution generation process, the input to the iteration may be the residue of the timeseries distribution 712 after extracting the previously-generated IMF distributions.

An operational example of performing EMD using a qualified recursion with a defined maximum IMF distribution count of four is depicted in FIG. 9. As depicted in FIG. 9, during a first EMD iteration 901, the timeseries distribution 712 is processed to generate a first IMF distribution 911 and a first iteration residue 912. Then, during a second EMD iteration 902, the first iteration residue 912 is processed to generate a second IMF distribution 921 and a second iteration residue 922. Afterward, during a third EMD iteration 903, the second iteration residue 922 is processed to generate a third IMF distribution 931 and a third iteration residue 932. Subsequently, during a fourth EMD iteration 904, the third iteration residue 932 is processed to generate a fourth IMF distribution 941 and a fourth iteration residue 942. Finally, because after the fourth EMD iteration 904 the maximum number of four IMF distributions have been generated, the decomposed timeseries distributions 715 are generated based at least in part on the four IMF distributions 911, 921, 931, and 941 and the fourth iteration residue 942, which is adopted as an error distribution value.

Returning to FIG. 7, the depicted process continues when the forecast input preparation unit 704 of the predictive data analysis computing entity 106 merges the exogenous variables 714 and the decomposed timeseries distributions 715 to generate a forecast input 716. In some embodiments, the forecast input 716 includes a formatted forecast input for each machine learning model utilized by the forecast unit 705 of the predictive data analysis computing entity 106, where each formatted forecast input for a machine learning model has been generated in accordance with at least some of the exogenous variables 714 and/or at least some of the decomposed timeseries distributions 715 in accordance with an input structure of the corresponding machine learning model.

The process depicted in FIG. 7 continues when the forecast unit 705 of the predictive data analysis computing entity 106 processes the forecast input 716 in accordance with a plurality of machine learning models to generate per-model predictive outputs 717. Each machine learning model of the plurality of machine learning model may be configured to process corresponding formatted forecast input in the forecast input 716 that is associated with the machine learning model to generate a corresponding per-model predictive output. Examples of suitable machine learning models that may be utilized by the forecast unit 705 include Random Forest models, Support Vector Regression models, Gradient Boosting Machine models, and Long Short Term Memory models.

The process depicted in FIG. 7 continues when the ensemble unit 706 of the predictive data analysis computing entity 106 combines the per-model predictive outputs 717 to generate the preliminary superior domain event data 718. The preliminary superior domain event data 718 may be determined based at least in part on a measure of distribution of the per-model predictive outputs 717, such as weighted average of the per-model predictive outputs 717, where the weights used to determine the weighted average may be statically-defined values, dynamically-determinable values, values determined using one or more training processes, and/or the like. While various embodiments of the present invention describe the machine learning component of generating the preliminary superior domain event data as being performed by ensembles of two or more machine learning models, a person of ordinary skill in the relevant technical field will recognize that in some embodiments any number of machine learning models may be utilized and that in some embodiments there may be no ensemble models to generate ensembled output based on outputs of two or more machine learning models.

In some embodiments, the preliminary superior domain event data include various per-ensemble prediction values and/or may be determined based at least in part on various per-ensemble prediction values, where each per-ensemble value may be determined based at least in part on aggregating output of a corresponding subset of the plurality of machine learning models. For example, the preliminary superior domain event data may be determined by aggregating a first per-ensemble value determined based at least in part on the per-model predictive outputs 717 of the Support Vector Regression model and the Random Forest model, a second per-ensemble value determined based at least in part on the per-model predictive outputs 717 of Gradient Boosting Machine model and the Random Forest model, and the per-model predictive outputs 717 of the Long Short Term Memory model.

Returning to FIG. 6, at step/operation 602, the predictive data analysis computing entity 106 determines simulated superior domain input data for the hierarchically superior geographic domain at the forecasting period based at least in part on the observed superior domain input data. The simulated superior domain input data may be a data object that describes simulated values of one or more data variables (e.g., one or more weather-describing variables, one or more disease-outbreak-frequency-describing variables, one or more claim-fling-frequency-describing variables, and/or the like) associated with a hierarchically superior geographic domain (e.g., a state) during a forecasting period (e.g., a future period as of the time of a forecast).

In some embodiments, simulated data variables characterizing the simulated superior domain input data may be the same as the observed data variables characterizing the observed superior domain input data. In some embodiments, simulated data variables characterizing the simulated superior domain input data may include a subset of the observed data variables characterizing the observed superior domain input data that are not deemed to have sufficiently reliable forecasts. For example, the simulated data variables characterizing the simulated superior domain input data may exclude weather-describing variables to the extent there are reliable weather forecast data related to the weather-describing variables for the forecasting period. In some embodiments, as depicted in the superior-domain event forecasting data object 500 of FIG. 5, the simulated superior domain input data 504 include claim-filing-describing variables (i.e., Claim Var. 1 and Claim Var. 2) but not weather-describing variables (i.e., Weather Var. 1 and Weather Var. 2).

In some embodiments, the simulated superior domain input data are generated using a simulation method, such as a Monte Carlo simulation method. In some embodiments, the simulated superior domain input data are generated using a Markov Chain Monte Carlo simulation method. In some embodiments, the simulated superior domain input data are generated using a Markov Chain Monte Carlo simulation method with Gibbs sampling. The Markov Chain Monte Carlo simulation method utilized to generate simulated superior domain input data may process the observed superior domain input data based at least in part on random samples from the observed superior domain input data and by using a probability density function that is proportional to a function mapping the observed superior domain input data to the observed superior domain event data.

In some embodiments, determining the simulated superior domain input data comprises determining, using a Gibbs-sampling-based Markov Chain Monte Carlo routine, a superior-domain-related probability distribution of the observed superior domain input data; determining inferred superior domain input data for the hierarchically superior geographic domain at the forecasting period based at least in part on the superior-domain-related probability distribution; and determining the simulated superior domain input data based at least in part on the inferred superior domain input data.

At step/operation 603, the predictive data analysis computing entity 106 determines the forecasted superior domain event data based at least in part on the preliminary superior domain event data and the simulated superior domain input data. In some embodiments, to determine the forecasted superior domain event data, the predictive data analysis computing entity 106 first determines a simulated superior domain event data by processing the simulated superior domain input data (e.g., in accordance with the predictive model described in relation to FIG. 7). Afterward, the predictive data analysis computing entity 106 adjusts the preliminary superior domain event data based at least in part on the simulated superior domain event data, e.g., based at least in part on a measure of deviation between the simulated superior domain event data and the preliminary superior domain event data. In some embodiments, adjusting the preliminary superior domain event data based at least in part on the simulated superior domain event data is configured to provide a tradeoff between the predictive inference performed at step/operation 401 and the predictive inference performed to determine the simulated superior domain event data.

In some embodiments, step/operation 603 may be performed in accordance with the process depicted in FIG. 10, which is a flowchart diagram of an example process for determining the forecasted superior domain event data based at least in part on the preliminary superior domain event data and the simulated superior domain input data. The process depicted in FIG. 10 begins at step/operation 1001 when the predictive data analysis computing entity 106 determines simulated superior domain event data based at least in part on the simulated superior domain input data.

In some embodiments, to determine the simulated superior domain event data, the predictive data analysis computing entity 106 processes the simulated superior domain input data in accordance with one or more machine learning models (e.g., in accordance with the one or more machine learning models defined by the predictive model described in relation to FIG. 7 and/or in accordance with the predictive model described in relation to FIG. 7).

At step/operation 1002, the predictive data analysis computing entity 106 determines a measure of deviation between the simulated superior domain event data and a preliminary superior domain event data (e.g., a preliminary superior domain event data determined in accordance with the techniques described in relation to step/operation 601 of FIG. 6). In some embodiments, the measure of deviation is a raw measure of difference between the simulated superior domain event data and the preliminary superior domain event data. In some embodiments, the measure of deviation is a measure of difference between the simulated superior domain event data and the preliminary superior domain event data in an instant case relative to an overall distribution of the simulated superior domain event data and the preliminary superior domain event data across a group of cases including the instant case. In some embodiments, the measure of deviation is a measure of difference between the simulated superior domain event data and the preliminary superior domain event data in an instant case relative to an overall distribution of the simulated superior domain event data and the preliminary superior domain event data across a group of cases excluding the instant case.

At step/operation 1003, the predictive data analysis computing entity 106 adjusts the preliminary superior domain event data based at least in part on the measure of deviation to determine the forecasted superior domain event data. In some embodiments, adjusting the preliminary superior domain event data based at least in part on the simulated superior domain event data is configured to provide a tradeoff between the predictive inference performed at step/operation 401 and the predictive inference performed to determine the simulated superior domain event data. In some embodiments, determining the noted tradeoff can be performed based at least in part on a weight value for each of the predictive inference performed at step/operation 401 and the predictive inference performed to determine the simulated superior domain event data, where the weight values may be determined based at least in part on user-supplied values, system configuration values, trained parameter values, and/or the like.

Returning to FIG. 4, at step/operation 402, the predictive data analysis computing entity 106 determines a forecasted inferior domain event data for each hierarchically inferior geographic domain associated with the hierarchically superior geographic domain. In some embodiments, forecasted inferior domain event data is a data object that describes a predicted likelihood of occurrence and/or a predicted frequency of occurrence of a corresponding event type in a corresponding forecasting period (e.g., a future period as of the time of a forecast) for a corresponding hierarchically inferior geographic domain. For example, particular forecasted inferior domain event data may describe the predicted frequency of filing of medical claims related to a particular zoonotic disease in a corresponding intra-state district in a future period. In the noted example, the intra-state district is a hierarchically inferior geographic domain associated with the noted exemplary forecasted inferior event data, while filing of a medical claim related to a particular zoonotic disease (e.g., bird flu) is an event type associated with the noted exemplary forecasted inferior domain event data.

In some embodiments, step/operation 402 may be performed in accordance with the process depicted in FIG. 11, which is a flowchart diagram of an example process for determining forecasted inferior domain event data for a particular hierarchically inferior geographic domain. The process depicted in FIG. 11 begins at step/operation 1101 when the predictive data analysis computing entity 106 generates an inferior domain event prediction model for the hierarchically inferior geographic domain based at least in part on observed inferior domain input data for the hierarchically inferior geographic domain at the observation period, where the inferior domain event prediction model is configured to generate predicted events based at least in part on prediction input data.

In some embodiments, determining the inferior domain event prediction model for a hierarchically inferior geographic domain of the plurality of geographic domains comprises determining a zero-inflated Poisson model data object for the observed inferior domain input data for the hierarchically inferior geographic domain and determining the inferior domain event prediction model based at least in part on the zero-inflated Poisson model data object. In some embodiments, to determine the inferior domain event prediction model, the predictive data analysis computing entity 106 processes the observed inferior domain input data for the hierarchically inferior geographic domain (e.g., zip-code-level medical claim information data for a particular category of medical claims) in order to offset the noted observed inferior domain input data based on observed inferior domain event data for the hierarchically inferior geographic domain (e.g., zip-code-level medical claim count data for a particular category of medical claims). Thereafter, the predictive data analysis computing entity 106 fits a zero-inflated count model on the data generated by offsetting the observed inferior domain input data in order to generate the inferior domain event prediction model.

In some embodiments, the observed inferior domain input data may be a data object that describes observed values of one or more data variables (e.g., one or more weather-describing variables, one or more disease-outbreak-frequency-describing variables, one or more claim-fling-frequency-describing variables, and/or the like) associated with a hierarchically inferior geographic domain (e.g., an intra-state district) during an observation period (e.g., a past period as of the time of a forecast). For example, particular observed inferior domain input data may describe the mean temperature of a corresponding intra-state district during each month of a multi-month observation period. As another example, particular observed inferior domain input data may describe the aggregate number of flu patients in a corresponding intra-state district during each month of a multi-month observation period. As a further example, particular observed inferior domain input data may describe the aggregate number of flu medical claims filed in a corresponding intra-state district during each month of a multi-month observation period.

In some embodiments, the inferior domain event prediction model for a corresponding hierarchically inferior geographic domain is configured to generate predicted events based at least in part on prediction input data related to the corresponding hierarchically inferior geographic domain. For example, the inferior domain event prediction model may be configured to generate forecasted inferior domain event data for the hierarchically inferior geographic domain at the forecasting period based at least in part on simulated inferior domain input data and using the inferior domain event prediction model.

In some embodiments, the inferior domain event prediction model may describe a distribution of one or more random variables describing likelihood of occurrence of one or more events (e.g., likelihood of outbreaks of one or more diseases) to particular input variables (e.g., particular input variables determined based at least in part on observed inferior domain input data). An example of an inferior domain event prediction model may be a model that predicts likely number of medical claim filings associated with a particular medical condition in an intra-state district based at least in part on at least one of weather data for the intra-state district, disease outbreak data for the intra-state district, overall claim filing for the intra-state district. If the medical particular condition is occasionally very rare (e.g., is a zoonotic disease), the inferior domain event prediction model may utilize a zero-inflated distribution, such as a zero-inflated Poisson distribution.

At step/operation 1102, the predictive data analysis computing entity 106 determines simulated inferior domain input data for the hierarchically inferior geographic domain at the forecasting period based at least in part on the observed inferior domain input data and observed inferior domain event data for the hierarchically inferior geographic domain at the observation period. The simulated inferior domain input data may be a data object that describes simulated values of one or more data variables (e.g., one or more weather-describing variables, one or more disease-outbreak-frequency-describing variables, one or more claim-fling-frequency-describing variables, and/or the like) associated with a hierarchically inferior geographic domain (e.g., an intra-state district) during a forecasting period (e.g., a future period as of the time of a forecast).

In some embodiments, simulated data variables characterizing the simulated inferior domain input data may be the same as the observed data variables characterizing the observed inferior domain input data. In some embodiments, simulated data variables characterizing the simulated inferior domain input data may include a subset of the observed data variables characterizing the observed inferior domain input data that are not deemed to have sufficiently reliable forecasts. For example, the simulated data variables characterizing the simulated inferior input data may exclude weather-describing variables to the extent there are reliable weather forecast data related to the weather-describing variables for the forecasting period.

The observed inferior domain event data may be a data object that describes a predicted likelihood of occurrence and/or a predicted frequency of occurrence of a corresponding event type in a corresponding observation period (e.g., a past period as of the time of a forecast). For example, particular observed inferior domain event data may describe the predicted frequency of filing of medical claims related to a particular zoonotic disease in a corresponding intra-state district in the past n months, where n may be a predefined and/or a trained hyperparameter of the predictive data analysis computing entity 106. In the noted example, the intra-state district is a hierarchically superior geographic domain associated with the noted exemplary observed inferior domain event data, while filing of a medical claim related to a particular zoonotic disease (e.g., bird flu) is an event type associated with the noted exemplary observed inferior domain event data.

In some embodiments, the simulated inferior domain input data are generated using a simulation method, such as a Monte Carlo simulation method. In some embodiments, the simulated inferior domain input data are generated using a Markov Chain Monte Carlo simulation method with Gibbs sampling. The Markov Chain Monte Carlo simulation method utilized to generate simulated inferior domain input data may process the observed inferior domain input data based at least in part on random samples from the observed inferior domain input data using a probability density function that is proportional to a function mapping the observed inferior domain input data to the observed inferior domain event data.

In some embodiments, determining the simulated inferior domain input data comprises determining, using a Gibbs-sampling-based Markov Chain Monte Carlo routine, an inferior-domain-related probability distribution of the observed inferior domain input data; determining inferred inferior domain input data for the hierarchically inferior geographic domain at the forecasting period based at least in part on the inferior-domain-related probability distribution; and determining the simulated inferior domain input data based at least in part on the inferred inferior domain input data.

Operational examples of observed inferior domain event data 1201, observed inferior domain input data 1202, simulated inferior domain input data 1203, and forecasted inferior domain event data 1204 are depicted in FIG. 12, which provides an operational example of an inferior-domain event forecasting data object 1200. As depicted in the inferior-domain event forecasting data object 1200 of FIG. 12, the observed inferior domain event data 1201, the observed inferior domain input data 1202, the simulated inferior domain input data 1203, and the forecasted inferior domain event data 1204 are associated with the hierarchically inferior geographic domain 1211 which describes a district within the state of New York. As further depicted in the inferior-domain event forecasting data object 1200 of FIG. 12, the observed inferior domain event data 1201 and the observed inferior domain input data 1202 are both associated with the observation period 1221, while the simulated inferior domain input data 1203 and the forecasted inferior domain event data 1204 are both associated with the forecasting period 1222.

Returning to FIG. 11, at step/operation 1103, the predictive data analysis computing entity 106 determines the forecasted inferior domain event data for the hierarchically inferior geographic domain at the forecasting period based at least in part on the simulated inferior domain input data and using the inferior domain event prediction model. In some embodiments, the predictive data analysis computing entity 106 processes input data generated based at least in part on the simulated inferior domain input data using the inferior domain event prediction model and generates the forecasted inferior domain event data for the hierarchically inferior geographic domain based at least in part on the output of the processing. In some embodiments, determining the forecasted inferior domain event data for a hierarchically inferior geographic domain of the plurality of geographic domains comprises processing the simulated inferior domain input data for the hierarchically inferior geographic domain in accordance with the inferior domain event prediction model for the hierarchically inferior geographic domain to generate the forecasted inferior domain event data.

Returning to FIG. 4, at step/operation 403, the predictive data analysis computing entity 106 determines confirmed inferior domain event data for each hierarchically inferior geographic domain of the plurality of hierarchically inferior geographic domains based at least in part on the forecasted inferior domain event data for the hierarchically inferior geographic domain. In some embodiments, the predictive data analysis computing entity 106 determines confirmed inferior domain event data for each hierarchically inferior geographic domain based at least in part on each forecasted inferior domain event data for a hierarchically inferior geographic domain of the plurality of hierarchically inferior geographic domains associated a particular the hierarchically superior geographic domain (e.g., based at least in part on a sum of each forecasted inferior domain event data for a hierarchically inferior geographic domain of the plurality of hierarchically inferior geographic domains associated with a particular hierarchically superior geographic domain, such as a sum of predicted insurance claim filing counts for a particular disease for each intra-state district of a state).

In some embodiments, determining the confirmed inferior domain event data for each hierarchically inferior geographic domain of the plurality of hierarchically inferior geographic domains associated a particular the hierarchically superior geographic domain comprises aggregating each forecasted inferior domain event data for a hierarchically inferior geographic domain of the plurality of hierarchically inferior geographic domains to generate inferred superior domain event data for the particular superior geographic domain; determining a measure of deviation between the forecasted superior domain event data for the particular superior geographic domain and the inferred superior domain event data for the particular superior geographic domain; and determining each confirmed inferior domain event data based at least in part on the measure of deviation.

In some embodiments, determining each confirmed inferior domain event data based at least in part on the measure of deviation comprises adopting each forecasted inferior domain event data for a hierarchically inferior geographic domain of the plurality of inferior geographic domains associated with a particular superior geographic domain if the measure of deviation falls below a threshold measure of deviation. For example, the predictive data analysis computing entity 106 may adopt a set of per-district predicted insurance claim filing counts for a particular disease in each district of a state if the sum of the per-district predicted insurance claim filing counts is sufficiently similar to a per-state predicted insurance claim filing counts for the particular disease in the noted state.

In some embodiments, determining each confirmed inferior domain event data based at least in part on the measure of deviation comprises adjusting at least one forecasted inferior domain event data for a hierarchically inferior geographic domain of the plurality of inferior geographic domains associated with a particular superior geographic domain based at least in part on the magnitude of the measure of deviation. For example, the predictive data analysis computing entity 106 may adjust each forecasted inferior domain event data for a hierarchically inferior geographic domain of the plurality of inferior geographic domains associated with a particular superior geographic domain in accordance with outputs of an adjustment model, where the adjustment model is configured to process the measure of deviation to generate an adjustment value for each forecasted inferior domain event data.

At step/operation 404, the predictive data analysis computing entity 106 performs one or more prediction-based actions based at least in part on each confirmed inferior domain event data. Examples of prediction-based actions include automated emergency declaration actions, automated implementation of precautionary actions, automated hospital preparation actions, automated insurance workforce management operational management actions, automated insurance server load balancing actions, automated call center preparation actions, automated hospital preparation actions, automated insurance plan pricing actions, automated insurance plan update actions, and/or the like.

In some embodiments, the one or more prediction-based actions comprises detecting an emergency condition associated with an event type associated with the cross-geographical event prediction based at least in part on each confirmed inferior domain event data; and, in response to detecting the emergency condition, generating one or more emergency event outbreak notifications for the event type. In some embodiments, the one or more prediction-based actions comprise detecting an emergency condition associated with an event type associated with the cross-geographical event prediction based at least in part on each confirmed inferior domain event data; and, in response to detecting the emergency condition, performing one or more service center operational load balancing operations for the event type.

In some embodiments, one or more prediction-based actions comprise determining, based at least in part on confirmed inferior domain event data, a confirmed inferior domain event prediction for each hierarchically inferior geographic domain of the plurality of hierarchically inferior geographic domains; and generating a cross-geographical event prediction user interface that displays, for each hierarchically inferior geographic domain of the plurality of hierarchically inferior geographic domains, the confirmed inferior domain event prediction for the hierarchically inferior geographic domain in association with a geographic region placement indication for the hierarchically inferior geographic domain.

An operational example of a cross-geographical event prediction user interface 1300 is presented in FIG. 13. As depicted in FIG. 13, the cross-geographical event prediction user interface 1300 indicates predicted likelihood of event occurrences (e.g., calculated based at least in part on confirmed inferior domain event predictions) for each intra-state district within the United States using coloring schemes described by the guide user interface element 1301 for the cross-geographical event prediction user interface 1300. While various embodiments of the present invention discuss cross-geographical event prediction user interfaces including per-inferior-domain event likelihood values (e.g., per-district event likelihood values), a person of ordinary skill in the relevant technology will recognize that cross-geographical event prediction user interfaces may include per-superior-state event likelihood values (e.g., per-state event likelihood values) in addition to or instead of per-inferior-domain event likelihood values.
