Anomaly comparison across multiple assets and time-scales

Abstract:

Methods, systems, and computer program products for anomaly comparison across multiple assets and time-scales are provided herein. A computer-implemented method includes obtaining time-series data for each one of a plurality of assets; determining, for each of a plurality of time scales, one or more segments of the time-series data for each one of the plurality of assets; generating a graph for each one of the time-scales, the graph representing similarities between the one or more segments of the plurality of assets for the respective time-scale; computing an isolation metric for each of the generated graphs for at least one of the plurality of assets; aggregating the computed isolation metrics for the at least one asset; and determining whether the at least one asset is anomalous, based at least in part on a comparison of the aggregated isolation metric to a threshold.
