FEATRANK

Feature ranking on individual performance for classification

    [I,F] = FEATRANK(A,CRIT,T)
      I = A*FEATRANK([],CRIT,T)

Input
A	input dataset
CRIT	string name of a method or untrained mapping, default 'NN'
T	validation dataset (optional)

Output
I	vector with sorted feature indices
F	vector with criteria values

Description

Feature ranking based on the training dataset A. CRIT determines  the criterion used by the feature evaluation routine feateval. If

the	dataset T is given, it is used as test set for feateval. In I
the	features are returned in decreasing performance. In F the
corresponding	values of feateval are given. Default: crit='NN'.
