Information processing device, information processing method, and program

Abstract

An information processing device classifies biological activity patterns of an animal. The information processing device includes an arithmetic circuit configured to receive a biological signal that is a detection result of a biological activity of the animal acquired by a sensor having a plurality of detection channels or a sensor unit including a plurality of sensors. The arithmetic circuit detects a quasi-periodic signal from the detection result, scales the quasi-periodic signal in a time direction, generates a scaled signal whose period has a predetermined value, decomposes the scaled signal into a plurality of frequency components, acquires pieces of chronological phase information of the multiple frequency components, and classifies the biological activity patterns based on the pieces of chronological phase information.
