Document Type and Number:
WIPO Patent Application WO/2024/036727
Kind Code:
A1
Abstract:
The present application provides a data anomaly detection method and apparatus, a device, a medium, and a program product. The method comprises: acquiring time sequence data corresponding to a time period in which detection is to be performed, performing periodic characteristic analysis on the time sequence data, and determining a decomposition period; according to the decomposition period, decomposing the time sequence data to obtain a plurality of sample sequences; according to a preset division manner, dividing each sample sequence into a plurality of sub-sequences, and combining the sub-sequences within the same time period into a voting time sequence to determine a plurality of voting time sequences corresponding to a plurality of different time periods; and using an anomaly detection model to perform anomaly detection on the voting time sequences, and according to a preset voting determination rule, determining whether detection results are anomalous. The technical problems in the existing data anomaly detection methods that the effect of anomaly detection on periodically changing financial accounting data is unstable, and the misjudgment rate is high are solved.
