Researchers have introduced a novel role-aware neural convex divergence head designed for asymmetric representation learning tasks. This new head projects source and target roles before calculating an input-convex neural Bregman divergence, producing a structured, non-negative score. Experiments across various benchmarks, including lexical, sentence, ontology, and directed graph tasks, demonstrate that this approach consistently enhances directional accuracy compared to standard methods while maintaining a zero observed negative divergence rate. While specialized baselines may perform better on certain large-scale tasks like citation prediction, the proposed head offers a structured and interpretable plug-in module for applications where directional relationships are critical.
