Quantized Adam with Error Feedback [PDF]
ACM Transactions on Intelligent Systems and Technology, 2021 In this article, we present a distributed variant of an adaptive stochastic gradient method for training deep neural networks in the parameter-server model. To reduce the communication cost among the workers and server, we incorporate two types of quantization schemes, i.e., gradient quantization and weight quantization, into the proposed distributed ...
