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 lie in vision-language models. I have also worked on domain adaptation and federated learning, and continue to explore these areas with strong interest.

How Dr. GRPO fixes two biases in GRPO: dividing by the response length makes long wrong answers cheap, and dividing by the group's standard deviation overweights questions that are too easy or too hard. Removing both recovers the unbiased policy gradient and stops responses from growing needlessly long.
How DAPO fixes the failures of GRPO in long chain-of-thought reasoning: Clip-Higher against entropy collapse, dynamic sampling against zero-gradient prompts, a token-level loss for long responses, and overlong reward shaping for truncated answers.
