Correspondence Transformers With Asymmetric Feature Learning and Matching Flow Super-Resolution

1 code implementation CVPR 2023 Yixuan Sun, Dongyang Zhao, Zhangyue Yin, Yiwen Huang, Tao Gui, Wenqiang Zhang, Weifeng Ge

The asymmetric feature learning module exploits a biased cross-attention mechanism to encode token features of source images with their target counterparts.

Attribute Surrogates Learning and Spectral Tokens Pooling in Transformers for Few-shot Learning

1 code implementation CVPR 2022 Yangji He, Weihan Liang, Dongyang Zhao, Hong-Yu Zhou, Weifeng Ge, Yizhou Yu, Wenqiang Zhang

To improve data efficiency, we propose hierarchically cascaded transformers that exploit intrinsic image structures through spectral tokens pooling and optimize the learnable parameters through latent attribute surrogates.

Multi-scale Matching Networks for Semantic Correspondence

1 code implementation ICCV 2021 Dongyang Zhao, Ziyang Song, Zhenghao Ji, Gangming Zhao, Weifeng Ge, Yizhou Yu

We follow the coarse-to-fine matching strategy and build a top-down feature and matching enhancement scheme that is coupled with the multi-scale hierarchy of deep convolutional neural networks.

Hierarchical Meta Reinforcement Learning for Multi-Task Environments

1 code implementation1 Jan 2021 Dongyang Zhao, Yue Huang, Changnan Xiao, Yue Li, Shihong Deng

To address the problem brought by the environment, we propose a Meta Soft Hierarchical reinforcement learning framework (MeSH), in which each low-level sub-policy focuses on a specific sub-task respectively and high-level policy automatically learns to utilize low-level sub-policies through meta-gradients.

Deep Hierarchical Reinforcement Learning Based Recommendations via Multi-goals Abstraction

no code implementations22 Mar 2019 Dongyang Zhao, Liang Zhang, Bo Zhang, Lizhou Zheng, Yongjun Bao, Weipeng Yan

To tackle this challenge, we propose a deep hierarchical reinforcement learning based recommendation framework, which consists of two components, i. e., high-level agent and low-level agent.
