About Me
- Hi, my name is Lai Wei (魏来) and I am a second-year PhD student at SJTU, majoring in computer science. Since AI is a subject that interests me greatly, I have been working on it throughout my academic journey. I am committed to staying abreast of new advances in AI and am always looking for novel approaches to innovate and push the boundaries in this field. My recent research focuses on the continual reinforcement learning of (multimodal) large language models.
