Experiment-based deep learning approach for power allocation with a programmable metasurface

no code implementations26 Jul 2023 Jingxin Zhang, Jiawei Xi, Peixing Li, Ray C. C. Cheung, Alex M. H. Wong, Jensen Li

Enabled by the tunability of a programmable metasurface, large sets of experimental data in various configurations can be collected for DNN training.

Bidirectionally Deformable Motion Modulation For Video-based Human Pose Transfer

1 code implementation ICCV 2023 Wing-Yin Yu, Lai-Man Po, Ray C. C. Cheung, Yuzhi Zhao, Yu Xue, Kun Li

To address these issues, we propose a novel Deformable Motion Modulation (DMM) that utilizes geometric kernel offset with adaptive weight modulation to simultaneously perform feature alignment and style transfer.

Dynamic Sparse Training: Find Efficient Sparse Network From Scratch With Trainable Masked Layers

1 code implementation ICLR 2020 Junjie Liu, Zhe Xu, Runbin Shi, Ray C. C. Cheung, Hayden K. -H. So

We present a novel network pruning algorithm called Dynamic Sparse Training that can jointly find the optimal network parameters and sparse network structure in a unified optimization process with trainable pruning thresholds.
