Research Intern

• LLM Server System

Research Intern

• Adivisors Prof. Weiming Zhang, Prof. Kejiang Chen
• Robust Image Watermark
• Proposed a watermark recovery module based on image hiding, designed to restore information-embedded images subjected to cropping and spatial manipulation.
• Completed experiments on the reproduction of related research and developed the code for the module framework as proposed by coworker.

Research Intern

• Adivisors Prof. Weiming Zhang, Postdoc. Zehua Ma
• Review on Diffusion Model Watermarking
• Learned the principles of diffusion model in depth, and explored works involved in embedding watermarks on images generated by diffusion models.
• Tried to design a guiding map to use the probability distribution information in the diffusion process of the Diffusion Model to optimize subsequent watermark embedding.

Semantic Guidance for Diffusion Model

• Conducted a detailed investigation into the semantic guidance of diffusion models, focusing on understanding both the theoretical underpinnings and experimental outcomes.
• Identified existing issues within the semantic guidance provided by diffusion models, particularly emphasizing the loss of positional information.
• Developed a straightforward method to address the loss of positional information in the semantic guidance of diffusion models, enhancing model accuracy and interpretability.
