Abstract
A model maintenance method is provided. If accuracy of prediction by a current model through consultation with new data is determined to be below a predetermined threshold, a compound model is formed by supplementing the current model with a local net trained with the new data.

23. A compound model of a system, comprising:
-
a current model; and
at least one local net having an associated valid data space, wherein when the compound model is consulted with a data point, the local net is consulted with the data point and a result of consulting the local net is returned, if the data point is within an associated valid data space of the local net, and the current model is consulted with the data point and a result of consulting the current model is returned, if the data point is not within the associated valid data space of the local net.
