Classification: CPC G | IPC G

Claim 18:
19. A computer program product, comprising:
a computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code executable by one or more computer processors to cause the one or more computer processors to perform an operation, the operation comprising:
receiving historical feature data relating to a plurality of nodes in a system;
generating a machine learning (ML) model for a node of the plurality of nodes, wherein the ML model is trained to predict a plurality of future feature values for the node based on at least a portion of the historical feature data;
generating a causal graph for the plurality of nodes using a feature selection mechanism within the ML model, wherein the feature selection mechanism comprises a regularization term encouraging sparsity of nodes in selected features in the ML model; and
at least one of: (i) detecting an anomaly in the system based on a prediction error relating to a predicted plurality of feature values or (ii) identifying a root cause for a fault in one of the plurality of nodes in the system based on the ML model, the causal graph, and the prediction error relating to the predicted plurality of future feature values,
wherein the prediction error is computed using a mean of norms of the difference between the predicted and the actual feature values for the node in question.
