TOV: The Original Vision Model for Optical Remote Sensing Image Understanding via Self-supervised Learning

no code implementations10 Apr 2022 Chao Tao, Ji Qia, Guo Zhang, Qing Zhu, Weipeng Lu, Haifeng Li

We believe that a general model which is trained by a label-free and task-independent way may be the next paradigm for RSIU and hope the insights distilled from this study can help to foster the development of an original vision model for RSIU.

Global and Local Contrastive Self-Supervised Learning for Semantic Segmentation of HR Remote Sensing Images

1 code implementation20 Jun 2021 Haifeng Li, Yi Li, Guo Zhang, Ruoyun Liu, Haozhe Huang, Qing Zhu, Chao Tao

Supervised learning for semantic segmentation requires a large number of labeled samples, which is difficult to obtain in the field of remote sensing.

Harnessing Structures for Value-Based Planning and Reinforcement Learning

1 code implementation ICLR 2020 Yuzhe Yang, Guo Zhang, Zhi Xu, Dina Katabi

In this paper, we propose to exploit the underlying structures of the state-action value function, i. e., Q function, for both planning and deep RL.

ME-Net: Towards Effective Adversarial Robustness with Matrix Estimation

1 code implementation28 May 2019 Yuzhe Yang, Guo Zhang, Dina Katabi, Zhi Xu

We show that this process destroys the adversarial structure of the noise, while re-enforcing the global structure in the original image.
