1. A method for classifying an input as belonging to one of a plurality of predefined classes, comprising:

  • (a) developing a plurality of feature values and forming a feature vector from the feature values which is representative of the input;

    (b) directly deriving curves of predictivity values from a reference database of inputs having pre-existing class annotations, to produce a knowledge base of principally learned classification information;

    (c) applying the feature vector to the knowledge-base for developing a plurality of predictivity values for each feature, each predictivity value being indicative of a likelihood of the input belonging to a respective one of each of said classes based on the feature value;

    (d) combining the predictivity values developed for each of the features for each class to generate a total predictivity value for each class; and

    (e) generating a determination of class based upon the total predictivity values generated by the prior step.
