Pytorch stochastic gradient descent
WebJul 14, 2024 · Gradient descent is an algorithm used to find the local minima value from a function. Local Minima can be defined as the lowest point of a particular function. This algorithm can be applied to various parametric models, such as linear regression. WebApr 11, 2024 · The momentum stochastic gradient descent uses the accumulated gradient as the updated direction of the current parameters, which has a faster training speed. …
