LOGLC

Trainable logistic linear classifier

    W = LOGLC(A)
    W = A*LOGLC

Input
 A Dataset

Output
 W Logistic linear classifier

Description

Computation of the linear classifier for the dataset A by maximizing the  likelihood criterion using the logistic (sigmoid) function.  This routine becomes very slow for feature sizes above 1000.
