Abstract:
A method for classifying portions of an input sequence of measurements into a plurality of regimes, given a set of possible switching states, comprising:associating each of a plurality of dynamic models with a switching state such that a dynamic model is selected when its associated switching state is true, wherein the switching state at a particular instance is determined by a switching model; decoupling the dynamic model from the switching model; determining parameters of the decoupled dynamic model, responsive to a switching state probability estimate; estimating a state of the decoupled dynamic model corresponding to a measurement at the particular instance, and responsive to the input sequence; determining parameters of the decoupled switching model, responsive to the dynamic state estimate; estimating a probability for each possible switching state of the decoupled switching model; determining a switching state sequence based on the estimated switching state probabilities; and classifying portions of the input sequence into different regimes, responsive to the determined switching state sequence.
