By fixing the representations of similar conflicting features to similar vectors, AE-SCL-SR provides a strong bias for h 1 and h 2 to be similar, as its only way to bias the predictions with respect to these features to be low is by pushing h 1 and h 2 to be similar.
under AE-SCL-SR the vectors that encode the non-pivot features of documents with similar pivot features are biased to be similar to each other.
