+ ## Model description
19
+
20
+ This model is based on [facebook/bart-large](https://huggingface.co/facebook/bart-large) and was finetuned on [SQuAD2.0](https://rajpurkar.github.io/SQuAD-explorer/). The corresponding papers you can found [here (model)](https://arxiv.org/pdf/1910.13461.pdf) and [here (data)](https://arxiv.org/abs/1806.03822).
