Nettet1. feb. 2024 · No, you don't have to restart your training. Changing the learning rate is like changing how big a step your model take in the direction determined by your loss function.. You can also think of it as transfer learning where the model has some experience (no matter how little or irrelevant) and the weights are in a state most likely better than a … Nettet19. jul. 2024 · Side note: I’d like the final learning rate to be 3e-5 after the warmup so I set the initial LR as 3e-5 and end_factor as 1 with initial factor being 0.05. This results in the final lr after warm up to be 1.5e-6 which is off by a factor of 20. I don’t quite understand why this happens, help on that would also be appreciated. Thanks. dayton wrenchNettetLinearLR. Decays the learning rate of each parameter group by linearly changing small multiplicative factor until the number of epoch reaches a pre-defined milestone: total_iters. Notice that such decay can happen simultaneously with other changes to the learning rate from outside this scheduler. When last_epoch=-1, sets initial lr as lr. dayton wound care clinic
