NAME¶
svm-scale - scale data to a restricted range as preprocessing for SVM training
SYNOPSIS¶
svm-scale [ -l lower ] [ -u upper ] [ -y
y_upper ] [ -s save_filename ] [ -r
restore_filename ] datafilename
DESCRIPTION¶
svm-scale reads the given
datafilename (a training or testing data
file as specified in
svm_train(1) or
svm_predict(1) ) and scales
all dimensions to the given ranges.
OPTIONS¶
- -l lower
- lower is the lowest (minimal) value allowed in each
dimension. It defaults to -1.
- -u upper
- upper is the highest (maximal) value allowed in each
dimension. It defaults to 1.
- -y y_lower
- y_lower is a boolean value (0 or 1) indicating
whether or not y-values (targets) should be scaled. It defaults to 0.
- -s save_filename
- save_filename indicates the filename to save the
scaled data to.
- -r restore_filename
- restore_filename indicates the filename reserved to
hold the original (unscaled) data in case there is a need to restore.
FILES¶
datafilename must be a training or testing dataset.
ENVIRONMENT¶
No environment variables.
DIAGNOSTICS¶
None documented; see Vapnik et al.
BUGS¶
Please report bugs to the Debian BTS.
