Greedy Coordinate Diffusion: Effective and Semantically Coherent Adversarial Attacks via Diffusion Guidance

Bohdan Turbal, Blossom Metevier, Max Springer +1

Adversarial attacks on large language models have limited practical impact despite extensive research. Optimization-based attacks such as Greedy Coordinate Gradient (GCG) (Zou et a…

Measuring Validity in LLM-based Resume Screening

Jane Castleman, Zeyu Shen, Blossom Metevier +2

Resume screening is perceived as a particularly suitable task for LLMs given their ability to analyze natural language; thus many entities rely on general purpose LLMs without furt…

The Geometry of Alignment Collapse: When Fine-Tuning Breaks Safety

Max Springer, Chung Peng Lee, Blossom Metevier +5

Fine-tuning aligned language models on benign tasks unpredictably degrades safety guardrails, even when training data contains no harmful content and developers have no adversarial…

Reinforcement Learning from Human Feedback with High-Confidence Safety Constraints

Yaswanth Chittepu, Blossom Metevier, Will Schwarzer +3

Existing approaches to language model alignment often treat safety as a tradeoff against helpfulness, which can lead to unacceptable responses in sensitive domains. To ensure relia…

Matched Pair Calibration for Ranking Fairness

Hannah Korevaar, Chris McConnell, Edmund Tong +6

We propose a test of fairness in score-based ranking systems called matched pair calibration. Our approach constructs a set of matched item pairs with minimal confounding differenc…

Enforcing Delayed-Impact Fairness Guarantees

Aline Weber, Blossom Metevier, Yuriy Brun +2

Recent research has shown that seemingly fair machine learning models, when used to inform decisions that have an impact on peoples' lives or well-being (e.g., applications involvi…

Reinforcement Learning When All Actions are Not Always Available

Yash Chandak, Georgios Theocharous, Blossom Metevier +1

The Markov decision process (MDP) formulation used to model many real-world sequential decision making problems does not efficiently capture the setting where the set of available…
