This is a RoBERTa-Large QA Model trained from https://huggingface.co/roberta-large in two stages. First, it is trained on synthetic adversarial data generated using a BART-Large question generator on Wikipedia passages from SQuAD as well as Wikipedia passages external to SQuAD, and then it is trained on SQuAD and AdversarialQA (https://arxiv.org/abs/2002.00293) in a second stage of fine-tuning.

Training data: SQuAD + AdversarialQA Evaluation data: SQuAD + AdversarialQA

Approx. 1 training epoch on the synthetic data and 2 training epochs on the manually-curated data.
