Abstract: A method, system and computer program product, the method comprising: mutually training, using feedback, a generator and a discriminator of a conditional adversarial generative adversarial networks using training item groups, each item group representing events in a time window, the generator comprises a generator Recurrent Neural Network (RNN), the discriminator comprises a discriminator RNN; receiving by the discriminator, discrete sequential data comprising a sequence of item groups comprising an item group representing events in a time window, and item groups representing events in preceding time windows; altering the sequence of item groups into collections of real numbers and providing them to the discriminator RNN; processing the collections by the discriminator RNN to obtain a probability for the item group to comprise an anomaly, in an unsupervised manner; and providing output to a user, the output based on the probability and indicative of a label for the discrete sequential data.

Abstract: A method, apparatus and product for automatic detection of anomalies in graphs. The method comprising obtaining training data, the training data comprising a plurality of graphs, each defined by nodes and edges connecting between the nodes, at least some of the nodes are labeled; determining a statistical model of a graph in accordance with the training data, the statistical model takes into account at least one structured and labeled feature of the graph, wherein the structured and labeled feature of the graph is defined based on a connection between a plurality of nodes and based on at least a portion of the labels of the plurality of nodes; obtaining an examined graph; and determining a score of the examined graph indicative of a similarity between the examined graph and the training data, wherein the score is based on a value of the structured and labeled feature in the examined graph.
