I would consider that already covered under the GDPR. Most machine learning approaches today make little to no guarantees about differential privacy and allow for (partial) extraction of the training dataset, which would mean that the request for deletion was never fully fulfilled.

So do you mean that GDPR allows for a request for removal from model or of there is an exemption from data mining results?

I think that it allows for a request for removal from the model unless it can be proven that the PII cannot be retrieved from the model.

(This should not be considered legal advice by me.)
