marf.FeatureExtraction.RawFeatureExtraction
Class RawFeatureExtraction

java.lang.Object
  marf.Storage.StorageManager
      marf.FeatureExtraction.FeatureExtraction
          marf.FeatureExtraction.RawFeatureExtraction.RawFeatureExtraction

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, IFeatureExtraction, IStorageManager

public class RawFeatureExtraction
extends FeatureExtraction

For a some applications it is desired to pass-through the preprocessed sample data "as-is", or with little massaging; this module does that. Note, unlike other feature extractor, in one of its modes of operation, RawFeatureExtraction allows arbitrary-length output in the pass-through mode, with which far not all classifiers can cope with.
