Title: Adaptive sensor model

Abstract: The invention provides a method of predicting output values of a physical system from a set of measured inputs of the system using an adaptive model. At each time when a prediction is made, the model is re-initialized to an initial, off-line model and is then refined to incorporate on-line data using a predetermined number of recent sets of measured inputs and outputs. The model thus always remains "tethered" to the initial, off-line model and if operating conditions remain steady, the model does not become too specific to those operating conditions.
