Anomaly detection and automated analysis using weighted directed graphs

Abstract:

A method includes receiving a data set. The data set includes a plurality of data subsets wherein each data subset is associated with one transaction in a fully or partially masked network. The method further includes processing each data subset according to a plurality of rules to generate a plurality of activation values and an output for the each data subset. The plurality of activation values and the output for the each data subset form an activation pattern for the each data subset. The method also includes generating a predictive model based on the activation patterns. The method further includes identifying a subset of transactions as outliers based on the predictive model.
