👋Hello there:)
I am Kaiyuan Liu (刘开元). I received my BE degree from Henan University, Henan, China, in 2023, and my MS degree in Data Science from the University of Macau, Macau, China, in 2025. I am currently working as a research assistant at the State Key Laboratory of IoTSC, University of Macau. My research interests center on MLsys, on-device LLM inference, and Edge computing. I am passionate about exploring how intelligent systems can be optimized for real-world applications and advancing the efficiency of AI on resource-constrained devices.

🧑💻 Research Experience
Edge LLM Collaborative Inference Framework
University of Macau, Jan. 2025 – May. 2025
This project focuses on developing a collaborative inference framework using idle neighboring devices to address memory and compute constraints in edge-device LLM deployment. We employ two-level optimization: inter-device coordination and intra-device resource utilization.
LLM Inference on Mobile Devices
University of Macau, Jun. 2024 – Dec. 2024
I am investigating ways to optimize LLM inference on mobile devices, addressing issues like high energy consumption and long inference times. The framework incorporates multi-dimensional optimization to balance performance, real-time efficiency, and energy consumption.
Chinese Sign Language Recognition Project
Henan University, Apr. 2021 – May. 2022
I led the development of a Chinese Sign Language recognition model that achieved 88% accuracy for 300 signs. This project won the National Innovation and Entrepreneurship Training award and contributed to one software copyright.
