Title:
INFORMATION PROCESSING DEVICE, CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/100285
Kind Code:
A1
Abstract:
An information processing device (2000) acquires a feature vector (20) acquired on the basis of signal data (14) of a detected value of a sensor (10) that performed sensing of gas to be measured. The information processing device (2000) resolves the feature vector (20) into a product of a coefficient vector and a feature matrix by non-negative matrix factorization (NMF). The detected value of the sensor (10) changes in accordance with adhesion and separation of molecules contained in the gas subjected to sensing. Values of respective elements of the feature vector (20) are equal to or larger than 0.
