How use multi-feature model for domain adaptation

Hi every body.
I searched in the forum but I didn’t find my answer.
I trained a general model using multi_feature transformer. I used POS tag as a extra feature. now I want to use this model for domain traininig.
first of all, is it possible?
if yes, how should I update my vocabs?

best regard.


Yes, as long as you can provide POS tags for the in domain data

It’s currently not possible the update the vocabulary of models with multiple inputs.

thank you for your answer.

I can provide POS tag for in domain data.

do you have any other sugession about how can I use this multi feature model for my in domain training?

You can start by just continuing the training on the new data and see if you get acceptable results.
