Natural Adversarial Patch Generation Method Based on Latent Diffusion Model

no code implementations27 Dec 2023 Xianyi Chen, Fazhan Liu, Dong Jiang, Kai Yan

Recently, some research show that deep neural networks are vulnerable to the adversarial attacks, the well-trainned samples or patches could be used to trick the neural network detector or human visual perception.

Offline Imitation from Observation via Primal Wasserstein State Occupancy Matching

1 code implementation2 Nov 2023 Kai Yan, Alexander G. Schwing, Yu-Xiong Wang

To address this problem, we propose Primal Wasserstein DICE (PW-DICE), which minimizes the primal Wasserstein distance between the expert and learner state occupancies with a pessimistic regularizer and leverages a contrastively learned distance as the underlying metric for the Wasserstein distance.

Language Agent Tree Search Unifies Reasoning Acting and Planning in Language Models

1 code implementation6 Oct 2023 Andy Zhou, Kai Yan, Michal Shlapentokh-Rothman, Haohan Wang, Yu-Xiong Wang

While large language models (LLMs) have demonstrated impressive performance on a range of decision-making tasks, they rely on simple acting processes and fall short of broad deployment as autonomous agents.

Neural-PBIR Reconstruction of Shape, Material, and Illumination

no code implementations ICCV 2023 Cheng Sun, Guangyan Cai, Zhengqin Li, Kai Yan, Cheng Zhang, Carl Marshall, Jia-Bin Huang, Shuang Zhao, Zhao Dong

In the last stage, initialized by the neural predictions, we perform PBIR to refine the initial results and obtain the final high-quality reconstruction of object shape, material, and illumination.

DML-GANR: Deep Metric Learning With Generative Adversarial Network Regularization for High Spatial Resolution Remote Sensing Image Retrieval

no code implementations7 Oct 2020 Yun Cao, Yuebin Wang, Junhuan Peng, Liqiang Zhang, Linlin Xu, Kai Yan, Lihua Li

With a small number of labeled samples for training, it can save considerable manpower and material resources, especially when the amount of high spatial resolution remote sensing images (HSR-RSIs) increases considerably.
