lr_multiplicative | R Documentation |
Multiply the learning rate of each parameter group by the factor given in the specified function. When last_epoch=-1, sets initial lr as lr.
lr_multiplicative(optimizer, lr_lambda, last_epoch = -1, verbose = FALSE)
optimizer |
(Optimizer): Wrapped optimizer. |
lr_lambda |
(function or list): A function which computes a multiplicative factor given an integer parameter epoch, or a list of such functions, one for each group in optimizer.param_groups. |
last_epoch |
(int): The index of last epoch. Default: -1. |
verbose |
(bool): If |
