RPFQ-ViT: Rotated Phase-Frame Quantization for Extremely Low-Bit Weights in Vision Transformers

Vision Transformers (ViTs) achieve strong performance on image recognition and mobile vision applications, but their high-dimensional linear projections and attention computations still impose substantial storage and inference costs. Extremely low-bit quantization is a promising solution, yet ViTs often suffer severe a...

REALHOP: Rethinking Multi-Hop Reasoning Evaluation via Behavioral Auditing

Results show that a conceptually coherent chain and a correct final answer do not by themselves establish multi-hop reasoning, and introduce REALHOP, a diagnose-construct-verify framework that rebinds entities, factorizes selected relations, adds complete competing paths, and places evidence at traceable locations.

Hy-MultiTurn: A Six-Dimensional Benchmark for Deep Multi-Turn Dialogue Understanding

This work analyzes real chatbot failures to identify six recurring mechanisms and defines six controlled evaluation modes in Hy-MultiTurn, a Chinese benchmark for deep multi-turn dialogue understanding, which shows that Hy-MultiTurn is broadly challenging.
