WebSep 26, 2024 · it is said that when regularization L2, it should only for weight parameters , but not bias parameters . (if regularization L2 is for all parameters, it’s very easy for the model to become overfitting, is it right?) But the L2 regularization included in most optimizers in PyTorch, is for all of the parameters in the model (weight and bias). WebOct 7, 2024 · The weight decay, decay the weights by θ exponentially as: θt+1 = (1 − λ)θt − α∇ft(θt) where λ defines the rate of the weight decay per step and ∇f t (θ t) is the t-th batch gradient to be multiplied by a learning rate α. For standard SGD, it is equivalent to standard L2 regularization.

WebTo construct an Optimizer you have to give it an iterable containing the parameters (all should be Variable s) to optimize. Then, you can specify optimizer-specific options such as the learning rate, weight decay, etc. Note If you need to move a model to GPU via .cuda (), please do so before constructing optimizers for it.
