WebCosineAnnealingLR explained. CosineAnnealingLR is a scheduling technique that starts with a very large learning rate and then aggressively decreases it to a value near 0 before increasing the learning rate again. Each time the “restart” occurs, we take the good weights from the previous “cycle” as the starting point. WebCosine annealing was initially developed for the Stochastic Gradient Descend ...
