Precise Information Control in Long-Form Text Generation

Jacqueline He, Howard Yen, Margaret Li +7

A central challenge in language models (LMs) is faithfulness hallucination: the generation of information unsubstantiated by input context. To study this problem, we propose Precis…

EvalTree: Profiling Language Model Weaknesses via Hierarchical Capability Trees

Zhiyuan Zeng, Yizhong Wang, Hannaneh Hajishirzi +1

An ideal model evaluation should achieve two goals: identifying where the model fails and providing actionable improvement guidance. Toward these goals for language model (LM) eval…
