WebOct 28, 2024 · The learning rate is increased linearly over the warm-up period. If the target learning rate is p and the warm-up period is n, then the first batch iteration uses 1 p/n for its learning rate; the second uses 2 p/n, and so on: iteration i uses i*p/n, until we hit the nominal rate at iteration n.

WebJul 19, 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.
