Auditing and Enforcing Conditional Fairness via Optimal Transport

AAAI 2025technical

Conditional demographic parity (CDP) is a measure of the demographic parity of a predictive model or decision process when conditioning on an additional feature or set of features. Many algorithmic fairness techniques exist to target demographic parity, but CDP is much harder to achieve, particularl…

Distributionally and Adversarially Robust Logistic Regression via Intersecting Wasserstein Balls

UAI 2025

Adversarially robust optimization (ARO) has emerged as the *de facto* standard for training models that hedge against adversarial attacks in the test stage. While these models are robust against adversarial attacks, they tend to suffer severely from overfitting. To address this issue, some successfu

Do LLMs Really Forget? Evaluating Unlearning with Knowledge Correlation and Confidence Awareness

NeurIPS 2025poster

Machine unlearning techniques aim to mitigate unintended memorization in large language models (LLMs). However, existing approaches predominantly focus on the explicit removal of isolated facts, often overlooking latent inferential dependencies and the non-deterministic nature of knowledge within LL…

Underestimated Privacy Risks for Minority Populations in Large Language Model Unlearning

ICML 2025poster

Large Language Models (LLMs) embed sensitive, human-generated data, prompting the need for unlearning methods. Although certified unlearning offers strong privacy guarantees, its restrictive assumptions make it unsuitable for LLMs, giving rise to various heuristic approaches typically assessed throu…
