Theoretical properties of sgd on linear model

Webb5 aug. 2024 · We are told to use Stochastic Gradient Descent (SGD) because it speeds up optimization of loss functions in machine learning models. But have you thought about … Webbing models, such as neural networks, trained with SGD. We apply these bounds to analyzing the generalization behaviour of linear and two-layer ReLU networks. Experimental study of these bounds provide some insights on the SGD training of neural networks. They also point to a new and simple regularization scheme

WebbThe main claim of the paper is that SGD learns, when training a deep network, a function fully explainable initially by a linear classifier. This, and other observations, are based on a metric that captures how similar are predictions of two models. The paper on the whole is very clear and well written.
