Question Answering Model in 2.13.0

Plugins Machine Learning
1

Hi all,

I saw the below in the documentation. I have three questions:

  1. Which model is this? is it available in huggingface so that we can easily finetune it?
  2. How to register other Q/A models in huggingface?
  3. Calling the model only return the output answer without showing the position of the answer in the context. Is there a way to return the position?

Thanks
