Abstract: Systems and methods for event prediction include converting event information into categorical time series data for a plurality of properties; determining relationships between pairs of properties of the plurality of properties based on a plurality of data types. A likelihood of an event occurring is predicted during a future period by summing over a Hawkes process for the pairs of properties, the Hawkes process taking as input the relationships between the pairs of properties and comparing the likelihood to an anomaly threshold that is based on a range of normal intensity values for transition sets based on the categorical time series data; and performing an action responsive to a determination that the likelihood exceeds the anomaly threshold.

Abstract: Systems and methods for creating a model include converting historical data into categorical time series data; de-noising the categorical time series data by organizing events into transition sets and removing noisy transitions sets according to a coefficient of variation. A relationship graph is generated that determines relationships between pairs of nodes, where the nodes relate to respective data sources and where the relationships indicate a degree of correlation between nodes based on the de-noised categorical time-series data, using a Hawkes process that determines a likelihood of a category transition based on historical events. An anomaly threshold is determined based on anomaly scores for a validation dataset using the relationship graph, wherein a likelihood output of the Hawkes process that exceeds the anomaly threshold indicates an anomaly.

Abstract: Systems and methods for pre-processing time series data include assigning transition events from categorical time series data into a list of transition sets that each include transitions from a respective first category to a respective second category and determining a mean duration and standard deviation, for each transition set, of the respective first category before the transition to the respective second category. A ratio is compared between the mean duration and the standard deviation to a threshold value to identify noisy transition sets; removing noisy transition sets from the list of transition sets to output de-noised transition sets. A probability of an event occurrence is predicted using the de-noised transition sets, and an action is performed responsive to the probability.
