Member Function Documentation

virtual dmatrix lti::featureSelector::apply (  const dmatrix &  src, const ivector &  srcIds )  const [virtual]

Extracts the best features of src copies them to dest. Parameters: src  dmatrix with the source data. srcIds  ivector with the ids corresponding to src Returns: the data set, that contains only the extracted features

virtual bool lti::featureSelector::apply (  const dmatrix &  src, const ivector &  srcIds, dmatrix &  dest )  const [pure virtual]

Extracts the best features of src copies them to dest. Parameters: src  dmatrix with the source data. srcIds  ivector with the ids corresponding to src dest  dmatrix where the result will be left. Returns: true if apply successful or false otherwise. Implemented in lti::plusLTakeAwayR, and lti::sffs.

virtual functor* lti::featureSelector::clone (   )  const [pure virtual]

returns a pointer to a clone of this functor. Implements lti::functor. Implemented in lti::plusLTakeAwayR, lti::sequentialBackwardSearch, lti::sequentialForwardSearch, and lti::sffs.

featureSelector& lti::featureSelector::copy (  const featureSelector &  other  )

copy data of "other" functor. Parameters: other  the functor to be copied Returns: a reference to this functor object

const parameters& lti::featureSelector::getParameters (   )  const

returns used parameters Reimplemented from lti::functor. Reimplemented in lti::plusLTakeAwayR, lti::sequentialBackwardSearch, lti::sequentialForwardSearch, and lti::sffs.

virtual const char* lti::featureSelector::getTypeName (   )  const [virtual]

returns the name of this type ("featureSelector") Reimplemented from lti::functor. Reimplemented in lti::plusLTakeAwayR, lti::sequentialBackwardSearch, lti::sequentialForwardSearch, and lti::sffs.

featureSelector& lti::featureSelector::operator= (  const featureSelector &  other  )

alias for copy member Parameters: other  the functor to be copied Returns: a reference to this functor object
