Entity embedding-based anomaly detection for heterogeneous categorical events

Abstract

A system and method are provided. The system includes a processor. The processor is configured to receive a plurality of events from network devices, the plurality of events including entities that are involved in the plurality of events. The processor is further configured to embed the entities into a common latent space based on co-occurrence of the entities in the plurality of events and model respective pairs of the entities for compatibility according to the embedding of the entities to form a pairwise interaction for the respective pairs of the entities. The processor is additionally configured to weigh the pairwise interaction of different ones of the respective pairs of the entities based on one or more compatibility criterion to generate a probability of an occurrence of an anomaly and alter the configuration of one or more of the network devices based on the probability of the occurrence of the anomaly.
