A highly motivated and aspiring researcher with a strong background in deep learning, with recent work centered on multimodal learning. Over the past few years, I have actively contributed to the field, publishing research articles in top-tier venues such as ACL and WACV. My primary research interests now lie in preference optimization and reinforcement learning for large language models. I have also worked on vision-language models, domain adaptation, and federated learning, and continue to explore these areas with strong interest.

How CPPO improves perception in vision-language models during reinforcement learning: it finds the tokens whose entropy rises most when the image is hidden, and trains them with a contrastive loss to stay stable under harmless image changes and to shift when the image's content is removed.
How PAPO teaches multimodal models to look at the image while they learn to reason: it adds a loss that rewards responses whose probability drops when the image is masked, and keeps that loss from being gamed with two entropy terms.
