Xiaozhe Yao

Xiaozhe Yao is a second-year doctoral student at Systems Group, Department of Computer Science, ETH Zurich advised by Prof. Dr. Ana Klimović. Working on a wide spectrum of machine learning and systems, his research direction is to build systems that support large-scale machine learning and democratize machine learning.

Prior to ETH Zurich, Xiaozhe Yao gained his Master’s degree at the University of Zurich in Data Science, advised by Prof. Dr. Michael Böhlen and Qing Chen. Before that, he completed his Bachelor’s study at Shenzhen University in Computer Science, advised by Prof. Dr. Shiqi Yu. He interned at Shenzhen Institute of Advanced Technology in 2016 as a data scientist. Between 2021 and 2022, he worked on the project AID as an Innovator Fellow at the Library Lab, ETH Zurich. The objective of AID is to support the application of machine learning algorithms by imitating a real library. It provides a unified programming interface to access and manage machine learning models, a digital library for searching, filtering and inspecting machine learning models.
