Member Function Documentation

unsigned int TupleDataSet::actionDim ( ) const

void TupleDataSet::init ( )

virtual

To be called before training. Should allocate example, among other things. Default version allocates example to the size of dim.

Reimplemented from DataSet.

unsigned int TupleDataSet::observationDim ( ) const

inline

void TupleDataSet::reset ( )

virtual

To be called before every episode.

Reimplemented from DataSet.

void TupleDataSet::setExample ( int  t )

virtual

Sets this->example to given index t.

Implements DataSet.
