Claim 19:
20. A system that characterizes susceptibility of an inferential model to follow signal degradation, comprising:
at least one processor and at least one associated memory; and
a prognostic-surveillance mechanism that executes on the at least one processor, wherein during operation, the prognostic-surveillance mechanism:
receives a set of time-series signals associated with sensors in a monitored system during normal fault-free operation;
trains the inferential model using the set of time-series signals; and
characterizes susceptibility of the inferential model to follow signal degradation, wherein during the characterization, the prognostic-surveillance mechanism,
adds degradation to a signal in the set of time-series signals to produce a degraded signal,
uses the inferential model to perform prognostic-surveillance operations on the set of time-series signals with the degraded signal, and
characterizes susceptibility of the inferential model to follow degradation in the signal based on results of the prognostic-surveillance operations.
