摘要
An acquisition unit (10) acquires normal sample data and non-normal sample data. A model generation unit (120) generates a normal model representing the normal sample data. A change unit (141) generates a non-normal feature vector of the non-normal sample data, and generates a non-normal changed vector obtained by changing an element of the non-normal feature vector. When the non-normal changed vector and the normal model are similar to each other, a verification unit (142) executes a process using sample data represented by the non-normal changed vector. The verification unit (142) verifies whether an anomalous event is detected by a detection device. Upon verification that an anomalous event is not detected, the verification unit (142) determines whether an anomalous event is present, independently of the detection device. Upon determination that an anomalous event is present, the verification unit (142) stores the sample data represented by the non-normal changed vector as missed-detection sample data (154) in a storage unit (150).
