WebApr 8, 2024 · Optimizers generate new parameter values and evaluate them using some criterion to determine the best option. Being an important part of neural network architecture, optimizers help in determining best weights, biases or other hyper-parameters that will result in the desired output. Webtorch.optim. torch.optim is a package implementing various optimization algorithms. Most commonly used methods are already supported, and the interface is general enough, so that more sophisticated ones can be also easily integrated in the future.
