A Good Plan is Hard to Find: Aligning Models with Preferences is Misaligned with What Helps Users

EMNLP 2025

To assist users in complex tasks, LLMs generate plans: step-by-step instructions towards a goal. While alignment methods aim to ensure LLM plans are helpful, they train (RLHF) or evaluate (ChatbotArena) on what users prefer, assuming this reflects what helps them. We test this with Planorama: an int

GRACE: A Granular Benchmark for Evaluating Model Calibration against Human Calibration

ACL 2025long

Language models are often miscalibrated, leading to confidently incorrect answers. We introduce GRACE, a benchmark for language model calibration that incorporates comparison with human calibration. GRACE consists of question-answer pairs, in which each question contains a series of clues that gradu…

Is your benchmark truly adversarial? AdvScore: Evaluating Human-Grounded Adversarialness

NAACL 2025long

Adversarial datasets should validate AI robustness by providing samples on which humans perform well, but models do not. However, as models evolve, datasets can become obsolete. Measuring whether a dataset remains adversarial is hindered by the lack of a standardized metric for measuring adversarial…

You Make me Feel like a Natural Question: Training QA Systems on Transformed Trivia Questions

EMNLP 2024main

Training question-answering QA and information retrieval systems for web queries require large, expensive datasets that are difficult to annotate and time-consuming to gather. Moreover, while natural datasets of information-seeking questions are often prone to ambiguity or ill-formed, there are trov…
