Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 15:
16. A computer program product for anomaly detection, comprising:
one or more non-transitory computer-readable storage media and program instructions stored on at least one of the one or more tangible storage media, the program instructions executable by a processor to cause the processor to perform a method comprising:
converting business process logs into a graphical data structure;
generating an optimized graph encoding for anomaly detection using an unsupervised machine learning method, wherein the optimized graph encoding is a result of continuously altering a graph encoding throughout a training process;
updating one or more hyperparameters of a graph autoencoder (GAE) using at least one or more learning rate optimization algorithms and a set of anomalous data, wherein the GAE simplifies the training process by recreating abstract structural process information;
computing an anomaly score for each activity of the business process log using a process aware metric-based on a feature representation; and
labeling each of one or more data points with a high anomaly score.
