Method Detail

onPassFinished

public boolean onPassFinished(int pass,
                              long iteration,
                              double cost,
                              de.jungblut.math.DoubleVector currentWeights)

Description copied from interface: PassFinishedCallback

This callback when a pass over a stream of a minimization objective is finished.

Specified by:

onPassFinished in interface PassFinishedCallback

Parameters:

pass - the number of the current pass.

iteration - the number of the current iteration.

cost - the validation error after the current pass. If no hold-out validation was chosen, it will be zero.

currentWeights - the current optimal weights.

Returns:

false if we should stop the whole computation after this pass, or true if continue.

onValidationFinished

                                 long iteration,
                                 double cost,
                                 de.jungblut.math.DoubleVector currentWeights,
                                 de.jungblut.online.ml.FeatureOutcomePair pair)

Description copied from interface: ValidationFinishedCallback

This callback when a pass over an example in a stream of a minimization objective is finished.

Specified by:

onValidationFinished in interface ValidationFinishedCallback

Parameters:

pass - the number of the current pass.

iteration - the number of the current iteration.

cost - the cost at the current iteration.

currentWeights - the current optimal weights.
