Overrides. ", "If >=0, uses the corresponding part of the output as the past state for next step. Even though I agree about the default value (it should probably be 0.01 as in the PyTorch implementation), this probably should not be changed without warning because it breaks backwards compatibility. gradients if required, and pass the result to apply_gradients. Hopefully this blog post inspires you to consider optimizing hyperparameters more when training your models. The output directory where the model predictions and checkpoints will be written.

I guess it is implemented in this way, because most of the time you decide in the initialization which parameters you want to decay and which ones shouldnt be decayed, such as here: In general the default of all optimizers for weight decay is 0 (I dont know why pytorch set 0.01 for just AdamW, all other optimizers have a default at 0) because you have to opt-in for weight decay. passed labels. And this gets amplified even further if we want to tune over even more hyperparameters!
