HyPE: Category-Aware Hypergraph Encoding with Persistent Edge Embeddings for Persona-Grounded Dialogue

In three linesHyPE introduces a hypergraph encoder for persona-grounded dialogue systems. The method structures persona attributes into category-induced hypergraphs and applies HyperGCN with Persistent Edge Embeddings (PEE). Evaluation on PersonaChat shows consistent improvements over baselines across GPT-2, LLaMA-3.2-3B, and Qwen2.5-3B.
