Overview of NUQSGD
In today’s age where the size and complexity of models and datasets are constantly increasing, efficient methods for parallel model training are in high demand. One such method is Stochastic Gradient Descent (SGD) which is widely used in data-parallel settings. However, when it comes to communication costs, SGD is quite expensive since it has to communicate gradients with a large number of other nodes, especially in the case of large neural networks.
