Abstract
A system and method for detecting anomalies in gaming patterns, including: obtaining a time series data related to events; extracting event features of the events; calculating a normalized density estimation for each of the events; assigning outlier probability for each of the events based on the normalized density estimation; determining that an event is an outlier event if the outlier probability of the event is above an outlier threshold; calculating, for each window of the time series data, a set of window features based on the outlier events in the window; modeling the window features by a generative model; assigning outlier confidence value for each of the suspected windows based on the distribution of the window features relatively to the generative model; and determining that a window is a suspected window if the outlier confidence value of the window is above a confidence threshold.
