WebJun 9, 2024 · When using pure SGD (without momentum) as an optimizer, weight decay is the same thing as adding a L2-regularization term to the loss. When using any other optimizer, this is not true. Weight decay (don't know how to TeX here, so excuse my pseudo-notation): w [t+1] = w [t] - learning_rate * dw - weight_decay * w.
