Hey, this is Yifei!

I am an undergraduate student at the University of Toronto, studying computer science and mathematics.

For my Professional Experience Year (PEY), I worked as a machine learning stack engineer at Cerebras Systems, a company building state-of-the-art computer systems for complex AI and deep learning applications . I had the privilege of collaborating with a team of passionate architects focused on performance optimization.

In Fall 2024, I began my first research project under the supervision of Professor Ashton Anderson, where we utilize large language models for knowledge graph completion and logical reasoning tasks and submit my first paper to the Web Conference. Currently, I am working with Professor Rahul G.Krishnan, focusing on evaluating and addressing distributional shifts in policy functions for optimal lab test ordering across hospitals.

I am still exploring my focus, but I am primarily interested in machine learning(ML) research and their applications in the field of science!
