svm-subset

svm-subset(1)							   User Manuals 						     svm-subset(1)

NAME

       svm-subset - a subset selection tool for LIBSVM

SYNOPSIS

       svm-subset [ -s method ] dataset number [ output1 ] [ output2 ]

DESCRIPTION

       Training  large data is time consuming. Sometimes one should work on a smaller subset first. The python script subset.py randomly selects a
       specified number of samples. For classification data, we provide a stratified selection to ensure the same class distribution in  the  sub-
       set.

OPTIONS

       -s method

       0      -- stratified selection (classification only) (default)

       1      -- random selection

       output1
	      The subset. If output1 is omitted, the subset will be printed on the screen.

       output2
	      The rest of data.

FILES

       See svm-train(1) for the format of dataset

EXAMPLES

	      svm-subset heart_scale 100 file1 file2

       From heart_scale 100 samples are randomly selected and stored in file1. All remaining instances are stored in file2.

BUGS

       Please report bugs to the Debian BTS.
