Abstract:
1. A method to reduce uncertainty bounds of predicting a remaining life of a probe using a plurality of diverse models for predicting the remaining life of the probe, the method comprising: generating a plurality of estimated remaining life outputs, wherein each of the estimated remaining life outputs is generated using a respective one of the diverse models; aggregating the estimated remaining life outputs via a fusion model; in response to the aggregating, predicting the remaining life of the probe, the predicted remaining life having reduced uncertainty bounds based on the aggregating; generating a signal corresponding to the predicted remaining life of the probe; and defining at least one of a parameter and a structure of the fusion model, wherein the defining step comprises: defining the parameter of the fusion model, the parameter comprising a weight corresponding to each of the diverse models, wherein the step of defining the parameter comprises: making available input conditions describing more than one region of a feature space; and defining a local weight corresponding to each of the more than one regions of the feature space.
