AFAIK now it is not possible to use the fine-tuned model to be retrained on a new set of labels. A workaround for this is to fine-tune a pre-trained model use whole (old + new) data with a superset of the old + new labels. Is true?
I know it’s more of an ML question than a specific question toward this package, but I will really appreciate it if anyone can refer me to some reference that explains this. Thank you in advance.
