FIXWTS

Name

fixwts -- M-weighted robust weight filter from network activations.

Synopsis

fixwts <long_error_file><output_pat_wts>

DESCRIPTION

Fixwts creates a set of unequal pattern weights. The unequal pattern weights make the least squares function more efficient for non-standard distributions of the output errors by giving less weight to outliers in the distribution. [ref. D.F.Andrews, Technometrics, 16 (1974) 523.]

OPTIONS

<long_error_file>

The long error output file from an MLP training run. (Usually the output of a training run for mlp.)

<output_pat_wts>

The pattern weights to be used in the next MLP training run. It would replace "fg_pat_wts" in the example directory test/pcasys/execs/mlp/mlp_dir.

EXAMPLE(S)

From test/pcasys/execs/fixwts/fixwts.src:

% fixwts ../mlp/mlp_dir/trn01l.err fixwts.out Takes the long error file (trn01l.err) from a mlp training run and computes a set of robust weights (fixwts.out) to use in the next training run.
