Nettet28. okt. 2024 · Furthermore, I find that trying to "learn the learning rate" using curvature is not effective. However, there is absolutely no inconsistency in arguing that given we have settled on a learning rate regimen, that how we should alter it as we change the mini-batch can be derived (and is experimentally verified by me) by the change in curvature.

Nettet18. jul. 2024 · There's a Goldilocks learning rate for every regression problem. The Goldilocks value is related to how flat the loss function is. If you know the gradient of the loss function is small then you can safely try a larger learning rate, which compensates for the small gradient and results in a larger step size. Figure 8. Learning rate is just right. NettetLearning rate dropout (LRD) is a new gradient descent technique to motivate faster convergence and better generalization. LRD aids the optimizer to actively explore in the parameter space by randomly dropping some learning rates (to 0); at each iteration, only parameters whose learning rate is not 0 are updated.
