1. A model detection apparatus for detecting a model from a series of input data, comprising:

  • a plurality of estimate parameter memories for respectively storing mutually different distribution estimate parameters representing occurrences of said input data;

    a plurality of distribution estimators respectively associated with said estimate parameter memories for producing a plurality of distribution estimate parameters from data stored in the associated estimate parameter memories and from said series of input data, and updating the associated estimate parameter memories with the produced distribution estimate parameters;

    a model series memory for storing a plurality of candidate models corresponding in number to said estimate parameter memories;

    a model series estimator for producing a plurality of candidate models from said series of input data, said distribution estimate parameters stored in said estimate parameter memories and said candidate models stored in said model series memory, and updating the model series memory with the produced candidate models; and

    an optimal model series calculator for calculating an optimal series of models from said plurality of candidate models stored in said model series memory.
