Abstract

An anomaly detection device includes: a process data obtaining unit that obtains process data of a process having a plurality of process characteristics; and an anomaly detection unit that detects an anomalous state of the process based on a degree of anomaly that indicates a difference between the obtained process data and a normal state of the process represented by feature information that represents a feature of normal process data for each of the process characteristics. The feature information that represents the normal state of the process is optimum feature information for each of the process characteristics found by evaluating a candidate of feature information based on an error between the normal process data and estimated process data calculated using the candidate of feature information, the candidate of feature information being generated for each of the process characteristics from a plurality of items of normal process data obtained when the process is in the normal state.
