Welcome to my academic website! I am Xiaoyu Xie, a fifth-year PhD candidate in Mechanical Engineering Department at Northwestern University. I am supervised by Prof. Wing Kam Liu. My research focuses on developing robust and flexible artificial intelligence (AI) algorithms to discover hidden patterns and knowledge from data in manufacturing, fluid mechanics, solid mechanics, and more complex systems. My research goal is to improve the interpretability, generalization, and small-dataset scalability of AI algorithms by incorporating fundamental scientific insights. My research in dimensionless learning is a prime example of this approach, as it incorporates fundamental physical invariance to discover multiple levels of knowledge through machine learning.
