"WebMultiStepLR explained. The MultiStepLR is a scheduling technique that decays the learning rate of each parameter group by gamma once the number of epochs reaches one of the milestones. Compared to the StepLR, which reduces the learning rate every N epochs, with the MultiStepLR, we can say when exactly we want to decrease the learning rate.
