Mimic The Raw Domain: Accelerating Action Recognition in the Compressed Domain

no code implementations19 Nov 2019 Barak Battash, Haim Barad, Hanlin Tang, Amit Bleiweiss

Central Server Free Federated Learning over Single-sided Trust Social Networks

1 code implementation11 Oct 2019 Chaoyang He, Conghui Tan, Hanlin Tang, Shuang Qiu, Ji Liu

$\texttt{DeepSqueeze}$: Decentralization Meets Error-Compensated Compression

no code implementations17 Jul 2019 Hanlin Tang, Xiangru Lian, Shuang Qiu, Lei Yuan, Ce Zhang, Tong Zhang, Ji Liu

Since the \emph{decentralized} training has been witnessed to be superior to the traditional \emph{centralized} training in the communication restricted scenario, therefore a natural question to ask is "how to apply the error-compensated technology to the decentralized learning to further reduce the communication cost."
