Claim One:
1. A method for evaluating an anomaly measurement x′ in a machine condition monitoring system including a processor, wherein measurements x i are evaluated in a one-class classifier having a decision region R 1 for the class C 1 such that an evaluation function ƒ(x) is greater than or equal to a threshold T for a measurement x within the region, and less the T outside the region, the method comprising the steps of: training the one-class classifier to establish the decision region R 1 from a set of training samples {x 1 , x 2 ,. .. , x N }; receiving the anomaly measurement x′; determining that the anomaly measurement is outside the region R 1 ; determining, using the processor, a distance from the measurement x′ to a boundary of the region R 1 ; and evaluating the anomaly measurement x′ based on the distance; wherein the step of determining a distance from the measurement x′ to the region R 1 is performed iteratively.
