public interface InvertibleTransform
extends DataTransform

A InvertibleTransform is one in which any given transformed vector can be inverse to recover an approximation of the original vector when using a transform that implements this interface. It may not be possible to perfectly reproduce the original data point: ie, this process may not be loss-less.

inverse

DataPoint inverse(DataPoint dp)

Applies the inverse or "reverse" transform to approximately undo the effect of DataTransform.transform(jsat.classifiers.DataPoint) to recover an approximation of the original data point.

Parameters:

dp - the transformed data point

Returns:

the original data point, or a reasonable approximation
