Claim 11:
12. A device comprising:
at least one processor; and
at least one memory including computer program code;
the at least one memory and the computer program code configured to, with the at least one processor, cause the device to:
perform 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 of the physical system; and
during an online learning phase, predicting a current mode based on the learned parameters of the unknown component, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the device at least to:
during the online learning phase, predict the current mode by solving:, j
