How Does Learning Rate Decay Help Modern Neural Networks

How Does Learning Rate Decay Help Modern Neural Networks. Learning rate decay (lrdecay) is a \emph{de facto} technique for training modern neural networks. If you need help experimenting with the learning rate for your model, see the post:

So, we basically want to specify our learning rate to be some decreasing functions of epochs. Implement and apply a variety of optimization. Tianshou, an elegant, flexible, and superfast pytorch deep reinforcement learning platform.

Instead, what we can do is decrease our learning rate, thereby allowing our network to take smaller steps — this decreased learning rate enables our network to descend into areas of the loss landscape that are “more optimal” and would have otherwise been missed entirely by our learning rate learning. As a reminder, this parameter scales the magnitude of our weight updates in order to minimize the network's loss function.

Kaichao you, mingsheng long, jianmin wang, michael i. So, it seems like having a larger learning rate towards the beginning helps to quickly approach a good solution, and having a smaller learning rate seems to help stay close to the ideal solution.

It starts training the network with a large learning rate and then slowly reducing/decaying it until local minima is obtained. The reason for my question is, that from a theoretical view i think that learning rate decay makes totally sense for a given static dataset on which a neural network is trained on, to stabilise and converge the training process.

There are actually two strategies for warmup, ref here. For reinforcement learning the dataset is created and extended throughout the learning process, such that the network. Weight decay works by adding a penalty term to the cost function of a neural network which has the effect of shrinking the weights during backpropagation.
