REJECTM

Rejection mapping

     W = REJECTM(A,FRAC)

Description

Train the threshold of a rejection mapping W such that a fraction FRAC of the training data A is rejected. Dataset A is usually the output of  a classifier. The mapping REJECTM will add one extra reject class.

     W = REJECTM(A,FRAC,REJNAME)

If desired, the rejected objects will be labeled REJNAME. Default is  REJNAME = 'reject'.

Example(s)

A = GENDATB; % create trainingset  W = LDC(A); % create supervised classifier  WR = REJECTM(A*W,0.05); % reject 5% of the data  SCATTERD(A); PLOTC(W*WR); % show
