I am a Ph.D. student in ANSR Lab, supervised by Chair Professor John C.S. Lui (ACM/IEEE Fellow, Fellow of HKAES) at the Department of Computer Science & Engineering, The Chinese University of Hong Kong (CUHK). Before that, I obtained my honor bachelor degree (Advanced Class, GPA: 3.95/4.0) from the Department of Electronics and Information Engineering at Huazhong University of Science and Technology (HUST).

Research

My research centers on “advancing machine learning for decision-making under uncertainty in AI systems”. By developing theoretically grounded frameworks, such as reinforcement learning, online learning, and multi-armed bandits, I strive to design efficient, scalable, and trustworthy algorithms.

My work bridges theoretical rigor with practical impact, with a particular focus on AI computing and communication applications. The ultimate goal is to develop intelligent agents capable of making optimal decisions in dynamic and uncertain environments. These agents have significant applications across various domains, such as:

• AI-empowered network optimization and edge/mobile/cloud computing architectures;
• Adaptive recommendation engines and multimedia content delivery systems;
• LLM/Embodied AI enhancement and scheduling through learning paradigms.

I always welcome discussions and collaborations. Feel free to reach out via email: “xiangxdai0 [at] gmail.com” (recommended) or “xxdai23 [at] cse.cuhk.edu.hk”.
