Spectral Invariant Learning for Dynamic Graphs under Distribution Shifts

1 code implementation NeurIPS 2023 Zeyang Zhang, Xin Wang, Ziwei Zhang, Zhou Qin, Weigao Wen, Hui Xue, Haoyang Li, Wenwu Zhu

In this paper, we discover that there exist cases with distribution shifts unobservable in the time domain while observable in the spectral domain, and propose to study distribution shifts on dynamic graphs in the spectral domain for the first time.

PIAT: Parameter Interpolation based Adversarial Training for Image Classification

no code implementations24 Mar 2023 Kun He, Xin Liu, Yichen Yang, Zhou Qin, Weigao Wen, Hui Xue, John E. Hopcroft

Besides, we suggest to use the Normalized Mean Square Error (NMSE) to further improve the robustness by aligning the clean and adversarial examples.

Compare learning: bi-attention network for few-shot learning

no code implementations25 Mar 2022 Li Ke, Meng Pan, Weigao Wen, Dong Li

Learning with few labeled data is a key challenge for visual recognition, as deep neural networks tend to overfit using a few samples only.
