Patent number: 11797668Abstract: 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.Type: GrantFiled: October 11, 2017Date of Patent: October 24, 2023Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Takumi Yamamoto, Keisuke Kito, Tomonori Negi, Kiyoto Kawauchi
