Language Models can Subtly Deceive Without Lying: A Case Study on Strategic Phrasing in Legislation

ACL 2025long

We explore the ability of large language models (LLMs) to engage in subtle deception through strategically phrasing and intentionally manipulating information. This harmful behavior can be hard to detect, unlike blatant lying or unintentional hallucination. We build a simple testbed mimicking a legi…

PersonaGym: Evaluating Persona Agents and LLMs

EMNLP 2025

Persona agents, which are LLM agents conditioned to act according to an assigned persona, enable contextually rich and user-aligned interactions across domains like education and healthcare.However, evaluating how faithfully these agents adhere to their personas remains a significant challenge, part

QualEval: Qualitative Evaluation for Model Improvement

NAACL 2024long

Quantitative evaluation metrics have been pivotal in gauging the advancements of AI systems like large language models (LLMs).However, due to the intricate nature of real-world tasks, a single scalar to quantify and compare performance trivializes the fine-grained nuances of model behavior. Addition…

C-STS: Conditional Semantic Textual Similarity

EMNLP 2023long main

Semantic textual similarity (STS) has been a cornerstone task in NLP that measures the degree of similarity between a pair of sentences, with applications in information retrieval, question answering, and embedding methods. However, it is an inherently ambiguous task, with the sentence similarity de…

Hyperbolic Image-text Representations

ICML 2023poster

Visual and linguistic concepts naturally organize themselves in a hierarchy, where a textual concept "dog" entails all images that contain dogs. Despite being intuitive, current large-scale vision and language models such as CLIP do not explicitly capture such hierarchy. We propose MERU, a contrasti…

Let GPT be a Math Tutor: Teaching Math Word Problem Solvers with Customized Exercise Generation

EMNLP 2023long main

In this paper, we present a novel approach for distilling math word problem solving capabilities from large language models (LLMs) into smaller, more efficient student models. Our approach is designed to consider the student model's weaknesses and foster a tailored learning experience by generating…
