Abstract

A method for warning an abnormality of a target object by using a self-organizing map prescribed by a plurality of nodes indicating a normal state of the target object includes acquiring detection data indicating a state of the target object, performing learning of the self-organizing map by using the detection data indicating a distance between a feature value and a node smaller than an abnormality threshold value predefined, storing the detection data indicating the distance larger than the abnormality threshold value in a storage unit as recorded data, and performing notification of the abnormality of the target object when the number of pieces of the recorded data stored in the storage unit reaches a predetermined number.
