This PipeOp works for any regression learner.
The idea is to consider the whole task as a Regression Task.
Hence, a numeric response vector is predicted for which crossvalidated rank thresholds are found using (nloptr)nloptr::nloptr to rank the predictions.
Returns a single PredictionOrdinal.
As a default, optimizes MeasureOrdinalCE.
Used for regression Predictions.
