CLEANDSET

Clean dataset for small class size behavior of classifiers

     [B,M,K,C,LABLIST,L,W] = CLEANDSET(A,N,U)

Input
 A Dataset
 N Minimum desired class size, default 1
 U Untrained fallback classifier, default ONEC

Output
 B Dataset with small and empty classes removed
 M Number of objects in B
 K Feature size of B
 C Number of classes in B
 LABLIST Label list of A
 L Classes of A still availiable in B
 W Trained fallback classifier

Description

This routine serves three purposes

  • It summarises a number of statements in the training parts of a  classifier in orer to make the source more readable.
  • Removal of small classes.
  • In case B does not contain at least two classes of the desired sample  size, the fallback classifier U is trained by A and returned in W.

This routine takes facilitates the handling of imcomplete training sets,  together with the support routines ONEC, ALLCLASS and, CLASSUSE.
