Abstract:
This behavior recognition device includes: a data generating unit which generates status information data on the basis of the status of a subject; a storage unit which stores a usage learning model; and a behavior identifying unit which identifies a behavior of a person on the basis of the status information data and the usage learning model. The status information data associate a pattern indicating a relationship between a plurality of elements representing the status, and the degree and duration thereof, with a behavior estimated from the status. The usage learning model includes a plurality of models associating, for a specific status, a pattern indicating the relationship between the plurality of elements and the degree and duration thereof, with a behavior estimated from the specific status. The behavior identifying unit extracts the model having the highest degree of fit to the status information data, from within the usage learning model, and determines the behavior of the person on the basis of the degree of fit of the extracted model.
