Title:
ANOMALOUS DATA DETECTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/036709
Kind Code:
A1
Abstract:
Embodiments of the present invention relate to an anomalous data detection method and apparatus. The method comprises: inputting W pieces of data to be detected that are distributed in W dimensions into target models corresponding to target dimensions, wherein a target model corresponding to any target dimension is obtained by means of sample data from which strong influence point data is removed; for any target model, if it is determined that the W pieces of data to be detected do not meet the target model, determining all dimensions included in the target model as anomalous dimensions; for any anomalous dimension, determining an anomalous probability that the anomalous dimension is determined as an anomalous dimension in each target model; and according to the anomalous probability, determining whether the data to be detected corresponding to the anomalous dimension is anomalous data. The presence of anomalous data among the W pieces of data to be detected can be detected, and which data of which dimension is anomalous data among the W pieces of data to be detected can also be accurately positioned. Therefore, automatic and accurate positioning of anomalous data is achieved, without the need of manual re-check.
