Title: BEHAVIOR IDENTIFICATION DEVICE, AIR CONDITIONER, AND ROBOT CONTROL DEVICE
Abstract:
Through the present invention, a behavior identification device is obtained whereby various behaviors can be identified without specifically defining in advance a component constituting part of a behavior. A behavior identification device for identifying a behavior of a subject using a sensor value measured by a sensor with respect to the behavior of the subject, there being provided a sensor value acquiring unit (10) for establishing a distribution of sensor values measured within a predetermined time, a component database (42) for storing a collection of basic distributions as basic components constituting part of the distribution of sensor values, a ratio calculation unit (21) for calculating first component ratios which are ratios of each of the basic distributions included in the distribution of sensor values, a component ratio database (43) for storing second component ratios determined in correlation with behaviors to be identified, and an identification unit (22) for comparing the first component ratios and the second component ratios and identifying a behavior, the basic distributions being established as distributions used as a basis for a case in which each of the distributions are treated as vectors, on the basis of the collection of distributions of sensor values acquired in advance with respect to each of a plurality of types of behaviors.
