Copyright-Protected Language Generation via Adaptive Model Fusion

ICLR 2025oral

The risk of language models reproducing copyrighted material from their training data has led to the development of various protective measures. Among these, inference-time strategies that impose constraints via post-processing have shown promise in addressing the complexities of copyright regulatio…

Doubly robust identification of treatment effects from multiple environments

ICLR 2025poster

Practical and ethical constraints often require the use of observational data for causal inference, particularly in medicine and social sciences. Yet, observational datasets are prone to confounding, potentially compromising the validity of causal conclusions. While it is possible to correct for b…

Efficient Randomized Experiments Using Foundation Models

NeurIPS 2025poster

Randomized experiments are the preferred approach for evaluating the effects of interventions, but they are costly and often yield estimates with substantial uncertainty. On the other hand, in silico experiments leveraging foundation models offer a cost-effective alternative that can potentially att…

Detecting critical treatment effect bias in small subgroups

UAI 2024poster

Randomized trials are considered the gold standard for making informed decisions in medicine. However, they are often not representative of the patient population in clinical practice. Observational studies, on the other hand, cover a broader patient population but are prone to various biases. Thus…

Privacy-Preserving Data Release Leveraging Optimal Transport and Particle Gradient Descent

ICML 2024poster

We present a novel approach for differentially private data synthesis of protected tabular datasets, a relevant task in highly sensitive domains such as healthcare and government. Current state-of-the-art methods predominantly use marginal-based approaches, where a dataset is generated from private…
