An Image Patch is a Wave: Phase-Aware Vision MLP

10 code implementations CVPR 2022 Yehui Tang, Kai Han, Jianyuan Guo, Chang Xu, Yanxi Li, Chao Xu, Yunhe Wang

To dynamically aggregate tokens, we propose to represent each token as a wave function with two parts, amplitude and phase.

Prioritized Architecture Sampling with Monto-Carlo Tree Search

1 code implementation CVPR 2021 Xiu Su, Tao Huang, Yanxi Li, Shan You, Fei Wang, Chen Qian, ChangShui Zhang, Chang Xu

One-shot neural architecture search (NAS) methods significantly reduce the search cost by considering the whole search space as one network, which only needs to be trained once.

Adapting Neural Architectures Between Domains

1 code implementation NeurIPS 2020 Yanxi Li, Zhaohui Yang, Yunhe Wang, Chang Xu

The power of deep neural networks is to be unleashed for analyzing a large volume of data (e. g. ImageNet), but the architecture search is often executed on another smaller dataset (e. g. CIFAR-10) to finish it in a feasible time.

Adversarially Robust Neural Architectures

no code implementations2 Sep 2020 Minjing Dong, Yanxi Li, Yunhe Wang, Chang Xu

We explore the relationship among adversarial robustness, Lipschitz constant, and architecture parameters and show that an appropriate constraint on architecture parameters could reduce the Lipschitz constant to further improve the robustness.

Neural Architecture Dilation for Adversarial Robustness

no code implementations NeurIPS 2021 Yanxi Li, Zhaohui Yang, Yunhe Wang, Chang Xu

With the tremendous advances in the architecture and scale of convolutional neural networks (CNNs) over the past few decades, they can easily reach or even exceed the performance of humans in certain tasks.

Trade-Off Between Robustness and Accuracy of Vision Transformers

no code implementations CVPR 2023 Yanxi Li, Chang Xu

Although deep neural networks (DNNs) have shown great successes in computer vision tasks, they are vulnerable to perturbations on inputs, and there exists a trade-off between the natural accuracy and robustness to such perturbations, which is mainly caused by the existence of robust non-predictive features and non-robust predictive features.

GPT Self-Supervision for a Better Data Annotator

no code implementations7 Jun 2023 Xiaohuan Pei, Yanxi Li, Chang Xu

In the one-shot tuning phase, we sample a data from the support set as part of the prompt for GPT to generate a textual summary, which is then used to recover the original data.

Neural Architecture Retrieval

1 code implementation16 Jul 2023 Xiaohuan Pei, Yanxi Li, Minjing Dong, Chang Xu

With the increasing number of new neural architecture designs and substantial existing neural architectures, it becomes difficult for the researchers to situate their contributions compared with existing neural architectures or establish the connections between their designs and other relevant ones.

Understanding Robustness of Visual State Space Models for Image Classification

no code implementations16 Mar 2024 Chengbin Du, Yanxi Li, Chang Xu

VMamba exhibits exceptional generalizability with out-of-distribution data but shows scalability weaknesses against natural adversarial examples and common corruptions.
