Role-Aware Neural Convex Divergence Heads for Asymmetric Representation Learning
He Huang, Lu Shen, Yunfeng Huang, Li Qi
Many representation learning problems involve directed relations, such as lexical entailment, sentence entailment, ontology hierarchy, and citation links. Standard Euclidean, cosine, and Mahalanobis heads are symmetric, while generic neural scorers can model directionality but pr…
