Variance Reduced Local SGD with Lower Communication Complexity

1 code implementation30 Dec 2019 Xianfeng Liang, Shuheng Shen, Jingchang Liu, Zhen Pan, Enhong Chen, Yifei Cheng

To accelerate the training of machine learning models, distributed stochastic gradient descent (SGD) and its variants have been widely adopted, which apply multiple workers in parallel to speed up training.

Faster Distributed Deep Net Training: Computation and Communication Decoupled Stochastic Gradient Descent

no code implementations28 Jun 2019 Shuheng Shen, Linli Xu, Jingchang Liu, Xianfeng Liang, Yifei Cheng

Nevertheless, although distributed stochastic gradient descent (SGD) algorithms can achieve a linear iteration speedup, they are limited significantly in practice by the communication cost, making it difficult to achieve a linear time speedup.

STL-SGD: Speeding Up Local SGD with Stagewise Communication Period

no code implementations11 Jun 2020 Shuheng Shen, Yifei Cheng, Jingchang Liu, Linli Xu

Distributed parallel stochastic gradient descent algorithms are workhorses for large scale machine learning tasks.

Communication-Efficient Distributed Learning with Local Immediate Error Compensation

no code implementations19 Feb 2024 Yifei Cheng, Li Shen, Linli Xu, Xun Qian, Shiwei Wu, Yiming Zhou, Tie Zhang, DaCheng Tao, Enhong Chen

However, existing compression methods either perform only unidirectional compression in one iteration with higher communication cost, or bidirectional compression with slower convergence rate.
