Special-term Research Fellow、Assistant Professor

Biography

Yang Yuan is now an assistant professor at IIIS, Tsinghua. He finished his undergraduate study at Peking University in 2012. Afterwards, he received his PhD at Cornell University in 2018, advised by Professor Robert Kleinberg. During his PhD, he was a visiting student at MIT/Microsoft New England (2014-2015) and Princeton University (2016 Fall). Before joining Tsinghua, he spent one year at MIT Institute for Foundations of Data Science (MIFODS) as a postdoc researcher. He works on AI+Healthcare, AI Theory and Applied Category Theory.


Personal honor:

Beijing Zhiyuan Young Scientists (2020)

2019 Forbes China 30 under 30 (Science List)


Research Direction

AI+healthcare, AI theory and applied category theory

·AI+healthcare

   Category theory is the theoretical foundation of our system.

   We start from traditional Chinese medicine (TCM), gradually add elements from modern medicine, and will finally build a new healthcare system that is purely data driven.

   The symptoms and medicines in TCM, are exactly two categories. The treatment of a disease is a functor from the symptom category to the medicine category.

·AI theory

   Use category theory to analyze the power of foundation models, learning of concept, and present a framework of general intelligence


Research topic

AI-Interpretability in Machine Learning

The rapid development of deep learning technology has brought revolutionary progress to many fields, and the performance of deep learning models even surpasses that of humans in many tasks, especially in fields like image recognition and natural language processing. Our research group is committed to exploring cutting-edge AI interpretability, striving to not only understand the results of deep learning, but also why these results are achieved. We also plan to deploy our research findings in medical scenarios, developing more reliable deep learning assisted diagnosis systems.
