Class SvmLight2FeatureVectorAndLabel

java.lang.Object
  cc.mallet.pipe.Pipe
      cc.mallet.pipe.SvmLight2FeatureVectorAndLabel

All Implemented Interfaces:

AlphabetCarrying, java.io.Serializable

public class SvmLight2FeatureVectorAndLabel
extends Pipe

This Pipe converts a line in SVMLight format to a Mallet instance with FeatureVector data and Label target. The expected format is target feature:value feature:value ... targets and features can be indices, as in SVMLight, or Strings. Note that if targets and features are indices, their indices in the data and target Alphabets may be different, though the data will be equivalent.
