DESCRIPTION
svm-scale
reads the given
datafilename
(a training or testing data file as specified in

- -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.

datafilename
must be a training or testing dataset.
