Claim 6:
7. A method comprising:
performing a classification-based diagnosis for at least one of detecting and predicting faults in a physical system using partial system model information, said partial system model information including at least one of a system topology and component behavior, wherein said classification-based diagnosis includes:
during an offline learning phase, learning parameters of an unknown component, wherein the learning of the parameters of the unknown component occurs by solving:, β
