Fourier Disentangled Space-Time Attention for Aerial Video Recognition

no code implementations21 Mar 2022 Divya Kothandaraman, Tianrui Guan, Xijun Wang, Sean Hu, Ming Lin, Dinesh Manocha

Our formulation uses a novel Fourier object disentanglement method to innately separate out the human agent (which is typically small) from the background.

Optimizing the Long-Term Average Reward for Continuing MDPs: A Technical Report

no code implementations13 Apr 2021 Chao Xu, Yiping Xie, Xijun Wang, Howard H. Yang, Dusit Niyato, Tony Q. S. Quek

cost), by integrating R-learning, a tabular reinforcement learning (RL) algorithm tailored for maximizing the long-term average reward, and traditional DRL algorithms, initially developed to optimize the discounted long-term cumulative reward rather than the average one.

Dynamic Region-Aware Convolution

no code implementations CVPR 2021 Jin Chen, Xijun Wang, Zichao Guo, Xiangyu Zhang, Jian Sun

More gracefully, our DRConv transfers the increasing channel-wise filters to spatial dimension with learnable instructor, which not only improve representation ability of convolution, but also maintains computational cost and the translation-invariance as standard convolution dose.

Fully Learnable Group Convolution for Acceleration of Deep Neural Networks

no code implementations CVPR 2019 Xijun Wang, Meina Kan, Shiguang Shan, Xilin Chen

Benefitted from its great success on many tasks, deep learning is increasingly used on low-computational-cost devices, e. g. smartphone, embedded devices, etc.
