    • QUOTE: This module implements a loader and dumper for the svmlight format

      This format is a text-based format, with one sample per line. It does not store zero valued features hence is suitable for sparse dataset.

      The first element of each line can be used to store a target variable to predict.

      This format is used as the default format for both svmlight and the libsvm command line programs.
