DominationLossExample

class DominationLossExample extends Example

Implements the domination loss function: it penalizes models that rank any of the badCandidates above any of the goodCandidates.

The actual loss used in this version is the maximum (margin-augmented) difference between goodCandidates and badCandidates.
