Yilin (Larry) Li (李亦林)
Hi! I'm Larry, a Data Scientist at Arteria AI and a Mechatronics Engineering graduate from the University of Waterloo with an AI Option. Previously, I worked as a Data Scientist at Telus and as a Machine Learning Engineer Intern at Huawei Canada.
Technical Focus
My work focuses on document extraction systems, multi-agent workflows, and production ML pipelines. I’m particularly interested in:
- Vision Language Models (VLMs) for document understanding
- Information retrieval and semantic search
- Applied reinforcement learning for decision-making systems
Fun fact: I got the CCOM performance certificate of Erhu (a traditional Chinese instrument) in grade 10!
