I am a first-year Physics PhD student at MIT and IAIFI, advised by Prof. Max Tegmark. I have interned at Microsoft Research Asia. Before that, I received my Bachelor's degree in physics from Peking University. Prior to that, my memories are sealed in my hometown, Wuhan.
I research on the intersection of artificial intelligence and physics in general. My research interests include: (1) AI for physics: extracting physical insights (e.g. conservation laws and symmetries) from data, improving prediction accuracy and sampling efficiency for data analysis in physics; (2) Physics for AI: developing effective theories to understand the dynamics and generalization of neural networks. Besides that, I am generally interested in applications of AI to chemistry, biology, vision, language, medicine and robotics. I am happy and open to any form of collaboration.
I love music and mobile photography in my leisure time, but also have great fun thinking about (somewhat philosophical) questions regarding the boundary (if any) between human & artificial intelligence, mathematical modeling of humanities and other nerdy stuff.
Physics-augmented Learning: A new paradigm beyond physics-informed learning (Ziming Liu, Yunyue Chen, Yuanqi Du and Max Tegmark)
Comment: we propose a learning framework which unifies the already successful physics-informed learning paradigm and a novel paradigm called physics-augmented learning.
Machine Learning Hidden Symmetries (Ziming Liu and Max Tegmark)
Comment: We present a method searching for hidden symmetries revealed by coordinate transformations parameterized by neural networks.
Machine-Learning Non-Conservative Dynamics for New-Physics Detection (Ziming Liu, Bohan Wang, Meng Qi, Wei Chen, Max Tegmark and Tie-Yan Liu)
Comment: We present Neural New-Physics Detector (NNPhD), a machine learning algorithm for decomposing conservative and non-conservative forces. NNPhD is a natural extension of Lagrangian Neural Network.
AI Poincaré: Machine Learning Conservation Laws from Trajectories. (Ziming Liu and Max Tegmark)
Comment: We present AI Poincaré, a machine learning algorithm for auto-discovering conserved quantities using trajectory data from unknown dynamical systems. We released our code on PyPI here, and you could simply install aipoincare package by typing in
pip install aipoincare.
