1. A pattern recognition method for classifying a continuous pattern representative of a physical activity or phenomenon to one or predetermined classes each indicating a combination of one or more predetermined subclasses, comprising:

  • a first step of determining a plurality of partial scores each indicating an estimate of logarithm of a posteriori odds that one of partial patterns of said continuous pattern is classified to one of said subclasses;

    a second step of determining accumulated scores each indicating summation of one or more of said partial scores; and

    a third step of classifying said continuous pattern into one of said predetermined classes based on said determined accumulated scores, whereinscores of any possible partial patterns are used, andthe partial patterns are not first isolated.
