Webclass AdamWDL (AdamW): r """ The AdamWDL optimizer is implemented based on the AdamW Optimization with dynamic lr setting. Generally it's used for transformer model. We use "layerwise_lr_decay" as default dynamic lr setting method of AdamWDL. “Layer-wise decay” means exponentially decaying the learning rates of individual layers in a top … Web11 jul. 2024 · Also note, you probably don't want weight decay on all parameters (model.parameters()), but only on a subset. See here for examples: Weight decay in the optimizers is a bad idea (especially with BatchNorm) Weight decay only for weights of nn.Linear and nn.Conv* Karpathy minGPT code [1] Decoupled Weight Decay …
