Learning Macroscopic Dynamics without Reconstructing Microscopic States
Zhichao Han, Yue Zhao, Qianxiao Li
Modeling the temporal evolution of macroscopic properties of complex systems is an important scientific task. To predict this evolution without full microscopic simulation, a commo…
Learning Permutation-invariant Macroscopic Dynamics
Zhichao Han, Mengyi Chen, Qianxiao Li
Accurately modeling the macroscopic dynamics of high-dimensional microscopic systems is of broad interest across the sciences. Many data-driven approaches learn a low-dimensional l…
Learning Physics-Consistent Material Behavior from Dynamic Displacements
Zhichao Han, Mohit Pundir, Olga Fink +1
Accurately modeling the mechanical behavior of materials is crucial for numerous engineering applications. The quality of these models depends directly on the accuracy of the const…
Collective Relational Inference for learning heterogeneous interactions
Zhichao Han, Olga Fink, David S. Kammer
Interacting systems are ubiquitous in nature and engineering, ranging from particle dynamics in physics to functionally connected brain regions. These interacting systems can be mo…
Learning Physics-Consistent Particle Interactions
Zhichao Han, David S. Kammer, Olga Fink
Interacting particle systems play a key role in science and engineering. Access to the governing particle interaction law is fundamental for a complete understanding of such system…
Adversarial Attack on Community Detection by Hiding Individuals
Jia Li, Honglei Zhang, Zhichao Han +3
It has been demonstrated that adversarial graphs, i.e., graphs with imperceptible perturbations added, can cause deep graph models to fail on node/graph classification tasks. In th…
Predicting Path Failure In Time-Evolving Graphs
Jia Li, Zhichao Han, Hong Cheng +4
In this paper we use a time-evolving graph which consists of a sequence of graph snapshots over time to model many real-world networks. We study the path classification problem in…
Deeper Insights into Graph Convolutional Networks for Semi-Supervised Learning
Qimai Li, Zhichao Han, Xiao-Ming Wu
Many interesting problems in machine learning are being revisited with new deep learning tools. For graph-based semisupervised learning, a recent important development is graph con…
Community Detection via Local Dynamic Interaction
Junming Shao, Zhichao Han, Qinli Yang
How can we uncover the natural communities in a real network that allows insight into its underlying structure and also potential functions? In this paper, we introduce a new commu…
