PRODC

Product combining classifier

   W = PRODC(V)
   W = V*PRODC

Input
V	Set of classifiers trained on the same classes

Output
W	Product combiner

Description

It defines the product combiner on a set of classifiers, e.g.  V=[V1,V2,V3] trained on the same classes, by selecting the class  which yields the highest value of the product of the classifier  outputs. This might also be used as A*[V1,V2,V3]*PRODC in which  A is a dataset to be classified.

If it is desired to operate on posterior probabilities, then the  input classifiers should be extended like V = V*CLASSC.

The base classifiers may be combined in a stacked way (operating  in the same feature space) by V = [V1,V2,V3,...] or in a parallel  way (operating in different feature spaces) by V = [V1;V2;V3;...].
