PyTorch AdamW optimizer · GitHub - Gist It has been proposed in `Adam: A Method for Stochastic Optimization`_. In PyTorch the implementation of the optimizer does not know anything about neural nets which means it possible that the current settings also apply l2 weight decay to bias parameters. In general this is not done, since those parameters are less likely to overfit. and returns the loss. test loss 2097×495 43.5 KB. Deciding the value of wd.
