  • Publication number: 20240106731
    Abstract: Aspects of the subject disclosure may include, for example, determining that one or more tests are to be executed for a core network of a telecommunications system, based on the determining, transmitting one or more test initiation commands to a set of user equipment (UEs) of a plurality of UEs communicatively coupled to the core network, wherein the one or more test initiation commands cause the set of UEs to execute the one or more tests, obtaining, from the set of UEs, results associated with the one or more tests, analyzing the results based on one or more machine learning (ML) models to identify a network issue, and responsive to the analyzing, performing one or more actions to address the network issue. Other embodiments are disclosed.

  • Publication number: 20230419183
    Abstract: The present disclosure relates to systems, non-transitory computer-readable media, and methods for utilizing trained machine learning models to generate digital asset availability predictions and client intent classifications for providing pre-emptive digital notifications to client devices. In particular, the disclosed systems can utilize a decision availability prediction machine learning model trained based on historical data to generate a predicted asset availability time for a client account. In addition, in one or more implementations the pre-emptive notification system utilizes an intent prediction machine learning model to generate a digital intent classification. The pre-emptive notification system analyzes the predicted asset availability time and the digital intent classification to generate a pre-emptive digital notification.

  • Patent number: 11138524
    Abstract: Cascaded, boosted predictive models trained using distinct sets of exogenous and endogenous features are configured to predict component of performance ratings of entities. From the distinct predicted components, the second entity's rating factor can be determined. A second entity's rating factor represents the specific contribution a second entity makes to his average performance rating, as distinct from the rating that an arbitrary or hypothetical second entity would obtain.

  • Patent number: 10673731
    Abstract: An event analysis system receives events in a time-series from a set of monitored systems and identifies a set of alert threshold values for each of the types of events to identify outliers in the time-series at an evaluated time. Portions of historic event data is selected to identify windows of event data near the evaluated time at a set of seasonally-adjusted times to predict the value of the event type. The alert threshold value may also account for a prediction based on recent, higher-frequency events. Using the alert threshold values for a plurality of event types, the event data is compared with the alert threshold values to determine an alert level for the data. The event data types are also clustered and displayed with the alert levels to provide a visualization of the event data and identify outliers when the new event data is received.

  • Patent number: 10301867
    Abstract: An anomaly detection system is provided in connection with a transport service. The anomaly detection system can monitor progress of the transport service using received location data from driver and/or user mobile devices. During the progress of the transport service, the anomaly detection system can determine a probable anomaly by determining that a geographic position of the driver's vehicle has remained static for a period of time exceeding a threshold period of time, and in response to determining the probable anomaly, transmit a notification message to at least one of the driver and user mobile devices.

  • Publication number: 20190139450
    Abstract: Trip is analyzed from a population of drivers in order to determine one or more indicators of one or more driving styles. The trip data may include sensor information obtained from one or more sensor devices which are present in a vehicle of each driver of the population. A driving style is determined for the driver during a monitored trip by analyzing sensor information obtained from one or more sensor devices of the driver during the trip for at least one of the indicators of the one or more driving styles.

  • Patent number: 10123199
    Abstract: An anomaly detection system is provided in connection with a transport service. The anomaly detection system can construct routine route profiles for individual users of the transport service using historical route data. The anomaly detection system can monitor a current route traveled by a user. The anomaly detection system can further identify a matching routine route profile of the respective user. The anomaly detection system can utilize the matching routine route profile to identify a probable anomaly in the current route. In response to detecting the probable anomaly, the anomaly detection system can enable a safety protocol to perform a number of actions.
