BIRNAT: Bidirectional Recurrent Neural Networks with Adversarial Training for Video Snapshot Compressive Imaging

1 code implementation ECCV 2020 Ziheng Cheng, Ruiying Lu, Zhengjue Wang, Hao Zhang, Bo Chen, Ziyi Meng, Xin Yuan

This measurement and the modulation masks are fed into our Recurrent Neural Network (RNN) to reconstruct the desired high-speed frames.

SnapCap: Efficient Snapshot Compressive Video Captioning

no code implementations10 Jan 2024 JianQiao Sun, Yudi Su, Hao Zhang, Ziheng Cheng, Zequn Zeng, Zhengjue Wang, Bo Chen, Xin Yuan

To address these problems, in this paper, we propose a novel VC pipeline to generate captions directly from the compressed measurement, which can be captured by a snapshot compressive sensing camera and we dub our model SnapCap.

Momentum Benefits Non-IID Federated Learning Simply and Provably

no code implementations28 Jun 2023 Ziheng Cheng, Xinmeng Huang, Pengfei Wu, Kun Yuan

When all clients participate in the training process, we demonstrate that incorporating momentum allows FedAvg to converge without relying on the assumption of bounded data heterogeneity even using a constant local learning rate.

Joint Graph Learning and Model Fitting in Laplacian Regularized Stratified Models

1 code implementation4 May 2023 Ziheng Cheng, Junzi Zhang, Akshay Agrawal, Stephen Boyd

Laplacian regularized stratified models (LRSM) are models that utilize the explicit or implicit network structure of the sub-problems as defined by the categorical features called strata (e. g., age, region, time, forecast horizon, etc.

MetaSCI: Scalable and Adaptive Reconstruction for Video Compressive Sensing

2 code implementations CVPR 2021 Zhengjue Wang, Hao Zhang, Ziheng Cheng, Bo Chen, Xin Yuan

To capture high-speed videos using a two-dimensional detector, video snapshot compressive imaging (SCI) is a promising system, where the video frames are coded by different masks and then compressed to a snapshot measurement.
