Benchmarking Reward Hack Detection in Code Environments via Contrastive Analysis

ICML 2026poster

Recent advances in reinforcement learning for code generation have made robust environments essential to prevent reward hacking. As LLMs increasingly serve as evaluators in code-based RL, their ability to detect reward hacking remains understudied. In this paper, we propose a novel taxonomy of rewar…

Browsing Lost Unformed Recollections: A Benchmark for Tip-of-the-Tongue Search and Reasoning

ACL 2025long

We introduce Browsing Lost Unformed Recollections, a tip-of-the-tongue known-item search and reasoning benchmark for general AI assistants. BLUR introduces a set of 573 real-world validated questions that demand searching and reasoning across multimodal and multilingual inputs, as well as proficient…

Perturbation Augmentation for Fairer NLP

EMNLP 2022main

Unwanted and often harmful social biases are becoming ever more salient in NLP research, affecting both models and datasets. In this work, we ask whether training on demographically perturbed data leads to fairer language models. We collect a large dataset of human annotated text perturbations and t…

droidlet: modular, heterogenous, multi-modal agents

ICRA 2021poster

In recent years, there have been significant advances in building end-to-end Machine Learning (ML) systems that learn at scale. But most of these systems are: (a) isolated (perception, speech, or language only); (b) trained on static datasets. On the other hand, in the field of robotics, large-scale…
