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.
