PROBLEM TO BE SOLVED : To perform failure detection in which it is rare to overlook a failure that should be detected although there are many cases in which a normal system is mistakenly detected as a failure, or conversely, and also to perform failure detection in which it is unlikely to mistakenly detect a normal system as a failure although a failure that should be detected is often overlooked, whatever policy a maintenance operator may have.
SOLUTION : A maintenance operator can set a failure detection sensitivity for an overall failure or an individual failure. The set value is reflected as a cost ratio imposed to the case used for learning exceeding a hyperplane in a feature space.
