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.
