The simplest way to implement any learning rate schedule is by creating a function that takes the lr parameter (float32), passes it through some transformation, and returns it.This function is then passed on to the LearningRateScheduler callback, which applies the function to the learning rate.. Now, …

Many of these … WebOct 21, 2024 · The parameters of the embedding extractors were updated via the Ranger optimizer with a cosine annealing learning rate scheduler. The minimum learning rate was set to \(10^{-5}\) with a scheduler’s period equal to 100K iterations and the initial learning rate was equal to \(10^{-3}\). It means: LR = 0.001; eta_min = 0.00005; T_max = 100K
