RoBERTa-base fine-tuned on SQuAD v1

This model was fine-tuned from the HuggingFace RoBERTa base checkpoint on SQuAD1.1. This model is case-sensitive: it makes a difference between english and English.

Details

Dataset	Split	# samples
SQuAD1.1	train	96.8K
SQuAD1.1	eval	11.8k

Fine-tuning

• Python: 3.7.5

• Machine specs:

Example Usage

from transformers import pipeline

qa_pipeline = pipeline(
    "question-answering",
    model="csarron/roberta-base-squad-v1",
    tokenizer="csarron/roberta-base-squad-v1"
)

predictions = qa_pipeline({
    'context': "The game was played on February 7, 2016 at Levi's Stadium in the San Francisco Bay Area at Santa Clara, California.",
    'question': "What day was the game played on?"
})

print(predictions)
# output:
# {'score': 0.8625259399414062, 'start': 23, 'end': 39, 'answer': 'February 7, 2016'}
