Statistical Guarantees of Group-Invariant GANs

no code implementations22 May 2023 Ziyu Chen, Markos A. Katsoulakis, Luc Rey-Bellet, Wei Zhu

Group-invariant generative adversarial networks (GANs) are a type of GANs in which the generators and discriminators are hardwired with group symmetries.

Sample Complexity of Probability Divergences under Group Symmetry

no code implementations3 Feb 2023 Ziyu Chen, Markos A. Katsoulakis, Luc Rey-Bellet, Wei Zhu

We rigorously quantify the improvement in the sample complexity of variational divergence estimations for group-invariant distributions.

SpecNet2: Orthogonalization-free spectral embedding by neural networks

1 code implementation14 Jun 2022 Ziyu Chen, Yingzhou Li, Xiuyuan Cheng

The current paper introduces a new neural network approach, named SpecNet2, to compute spectral embedding which optimizes an equivalent objective of the eigen-problem and removes the orthogonalization layer in SpecNet1.

Representation-Agnostic Shape Fields

1 code implementation ICLR 2022 Xiaoyang Huang, Jiancheng Yang, Yanjun Wang, Ziyu Chen, Linguo Li, Teng Li, Bingbing Ni, Wenjun Zhang

In this study, we present Representation-Agnostic Shape Fields (RASF), a generalizable and computation-efficient shape embedding module for 3D deep learning.

Significant Inverse Magnetocaloric Effect induced by Quantum Criticality

no code implementations17 Feb 2021 Tao Liu, Xin-Yang Liu, Yuan Gao, Hai Jin, Jun He, Xian-Lei Sheng, Wentao Jin, Ziyu Chen, Wei Li

Strong fluctuations in the low-$T$ quantum critical regime can give rise to a large thermal entropy change and thus significant cooling effect when approaching the QCP.
