WebOct 24, 2024 · Top-K sparsification is one of the most popular gradient compression methods that sparsifies the gradient in a fixed degree during model training. However, there lacks an approach to adaptively adjust the degree of sparsification to maximize the potential of model performance or training speed. WebDec 4, 2024 · 4 Layer-Level Gradient Sparsification In this section, we propose to use an efficient layer-level threshold solution. Compared to the original version of gradient sparsification, we introduce the layer-level Top-k selection. In each iteration, each worker handles its local gradients layer-by-layer before broadcasting, and Eq. WebJan 14, 2024 · Top- sparsification can zero-out a significant portion of gradients without impacting the model convergence. However, the sparse gradients should be transferred with their irregular indices, which makes the sparse gradients aggregation difficult. briggsys butcher
