ABSTRACT:
An anomaly discriminating apparatus of the present invention comprises: first and second detecting devices for detecting state values of one event; and a processing device storing occurrence probability distribution group data which is a set of occurrence probability distributions of state values probably detected by the second detecting device against an arbitrary state value detected by the first detecting device, the processing device reading an occurrence probability on an occurrence probability distribution determined by a first state value detected by the first detecting device and a second state value detected by the second detecting device, the processing device determining whether at least either one of the first and second detecting devices is anomalous, based on a plurality of occurrence probabilities read out at different timings.
