Abstract
An action recognition system includes a controller that computes, in a time division manner, a plurality of feature vectors using as feature quantities information of a machine with respect to running that varies in a time sequence, generates a classification model by classifying the feature vectors into a plurality of clusters and allocating identification IDs to the clusters, generates an ID pattern model by allocating the identification IDs to the feature vectors computed in the time division manner on the basis of the classification model and associating a pattern of the identification IDs that vary in a time sequence according to a predetermined action of the machine with identification information of the predetermined action, generates output information for recognizing the predetermined action on the basis of changes in the identification IDs in the time sequence and the ID pattern model, and controls the display device to output the output information.
