Collapse or Thrive: Perils and Promises of Synthetic Data in a Self-Generating World

ICML 2025poster

What happens when generative machine learning models are pretrained on web-scale datasets containing data generated by earlier models? Some prior work warns of “model collapse” as the web is overwhelmed by synthetic data; other work suggests the problem can be contained (i.e. collapse can be avoided…

Model Editing as a Robust and Denoised variant of DPO: A Case Study on Toxicity

ICLR 2025poster

Recent alignment algorithms such as direct preference optimization (DPO) have been developed to improve the safety of large language models (LLMs) by training these models to match human behaviors exemplified by preference data. However, these methods are both computationally intensive and lacking…
