Model weights for a study of commonsense reasoning

This resource contains model weights for five Transformer-based models: [roBERTa](https://huggingface.co/docs/transformers/model_doc/roberta), [GPT-2](https://huggingface.co/docs/transformers/model_doc/gpt2), [T5](https://huggingface.co/docs/transformers/model_doc/t5), [BART](https://huggingface.co/docs/transformers/model_doc/bart) and [COMET](https://aclanthology.org/P19-1470/).These models were implemented using [HuggingFace](https://huggingface.co/), and fine-tuned on the following four commonsense reasoning tasks: Argument Reasoning Comprehension Task (ARCT), AI2 Reasoning Challenge (ARC), Physical Interaction Question Answering (PIQA) and CommonsenseQA (CSQA). The models are available for download form the PORTULAN repository.
