Finally, we will try using a Cyclic Learning Rate (CLR) schedule using the learning rate boundaries (1e-6, 3e-1). It also takes a long time to train them. 我用64 * 64大小的图像（微调了ImageNet）训练模型，解冻了一些层，应用 cyclic learning rate和snapshot ensembling，采用模型的权重，改变图片尺寸为299 * 299，再以64*64图像的权重进行微调，执行snapshot ensembling和热重启学习率。. I am wondering if it’s possible to create a custom schedule that works like ReduceLROnPlateau, where it is looking to see if the loss stops decreasing for some number of epochs, and if so then it decreases the LR. … instead of using a fixed value for learning rate and decreasing it over time, if the training doesn't improve our loss anymore, we're going to be changing the learning rate every iteration according to some cyclic function f. ), after about 180000 and 205000 gradient steps respectively. Condition (3) simply avoids cycles after unfolding. class OneCycleLR (_LRScheduler): r """Sets the learning rate of each parameter group according to the 1cycle learning rate policy.
