How refit on train+val set?

[EdgedSquirrels]

How should I refit the model on the whole dataset containing both training and validation sets?

It seems that both nf.fit and nf.cross_validation don't support this feature, but AutoModels have refit_with_val. Could I set refit_with_val on non-auto models?

You can simply combine both sets into a single dataframe and pass it to the fit method. Alternatively, if you used val_size, simply set it to 0 to use all of the data.

With cross_validation, you can use the refit parameter and it to True.

Hi @marcopeix,

Thanks for your answer. I’m not sure that when early stopping is enabled, will the number of training steps recorded and used during refit, or it will use max_steps during refit?

Also I’ve tried cross_validation with refit=True, but I only saw a progress bar running without another progress bar running after that. I’m not sure that whether cross_validation supports refit when val_size is given instead of n_windows.
