Title:
DETECTION METHOD, DETECTION PROGRAM, AND INFORMATION PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/079436
Kind Code:
A1
Abstract:
When data has been input into a first detection model of a plurality of detection models that have learned a determination boundary for classifying data feature space into a plurality of application regions, this information processing device acquires a first output result indicating in which one of the plurality of application regions the input data is located, on the basis of a plurality of sets of training data corresponding to a plurality of classes. When data has been input into a second detection model of the plurality of detection models, the information processing device acquires a second output result indicating in which one of the plurality of application regions the input data is located. On the basis of the first output result and the second output result, the information processing device detects data that causes degradation of the accuracy of the output result of a learned model as a result of changes in streamed data over time.
