Rubin Wei

I’m a first-year Ph.D student in Computer Science at the School of Artificial Intelligence, Shanghai Jiao Tong University (SJTU), advised by Prof. Zhouhan Lin in the Language Understanding and Machine Intelligence Algorithms (LUMIA) Group. Previously, I received my B.E. in Information Security from Wuhan University.

My research interests lie in machine learning and large language models (LLMs), particularly in:

• Memory-augmented LLMs — training long-term memory to retain the entire training dataset
• Parametric retrieval architectures for efficient and adaptive knowledge access
• Decoupling common and factual knowledge within LLMs

I’m always open to discussions and collaborations — feel free to reach out if you’d like to chat!
