Title:
IMPORTANCE DEGREE CALCULATION DEVICE, IMPORTANCE DEGREE CALCULATION METHOD, AND IMPORTANCE DEGREE CALCULATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/038722
Kind Code:
A1
Abstract:
A potential expression calculation unit (131) calculates potential expressions of data samples by using an encoder portion of a trained autoencoder. An importance degree calculation unit (133) calculates importance degrees respectively for features included in data samples on the basis of a gradient of the data samples with respect to the potential expressions.
