Abstract
To improve promptness of anomaly detection after occurrence of an event, provided is an anomaly detection apparatus including a processor that executes a program and a storage device that stores the program. The processor executes a correction process of applying a scale transformation to correct second predicted data in time-series first predicted data of a monitoring target, the second predicted data including data after occurrence time of a specific event, and a detection process of detecting an anomaly of the monitoring target based on the second predicted data corrected in the correction process and based on second measured data in time-series first measured data of the monitoring target, the second measured data including data after the occurrence time of the specific event.
