Use the discriminator of the model after training

[matteoguarrera]

Problem Description

It seems that the library does not have the possibility to use the discriminator after the training. Is it true?

Expected behavior

I believe that it is possible to add a score function like score_samples(X) that enables the user to see the GAN discriminator
output for a given sample.

Hi @matteoguarrera, you are correct, we currently do not plan to give access to the discriminator after training.

Thanks @fealho for the answer. I can do that and request a pull if you are interested.

I'm glad to hear you would be willing to contribute to the project! Unfortunately, I don't believe this feature is a priority at the moment. Maybe in the future, if more people show interest, we may implement it in SDV, but for now you don't need to worry about it.

I think this would be useful too. It could be used for checkpointing and early stopping on a validation set held out of the real dataset.

Would also be interested in using the discriminator afterwards. Is there any chance to save the trained discriminator to rerun it on unseen data?

Same here, even if just to get the model structure of discriminator for documentation purposes.

Hi, I have a great interest on this feature also !
