Treat Different Negatives Differently: Enriching Loss Functions with Domain and Range Constraints for Link Prediction

2 code implementations1 Mar 2023 Nicolas Hubert, Pierre Monnin, Armelle Brun, Davy Monticolo

In an extensive and controlled experimental setting, we show that the proposed loss functions systematically provide satisfying results which demonstrates both the generality and superiority of our proposed approach.
