Model description

This model is a fine-tuned version of deepset/roberta-base-squad2 on an squad dataset.It's been trained on question-answer pairs, including unanswerable questions, for the task of Question Answering for 6 Epochs. It achieves the following results after training:

• Train Loss: 0.1434
• Validation Loss: 0.4821

Model Training

• Training Dataset: squad
• Pretrained Model: deepset/roberta-base-squad2

Evaluation

The model's performance can be evaluated using various metrics such as Accuracy, Recall, Precision, F1 score.

• Precision: 0.9099
• Recall: 0.9099
• F1 Score: 0.9603

Example Usage

from transformers import pipeline

model_name = "Kiran2004/Roberta_QCA_Squad"

question_answerer = pipeline("question-answering", model = model_name)

question = "How many programming languages does BLOOM support?"
context = "BLOOM has 176 billion parameters and can generate text in 46 languages natural languages and 13 programming languages."

question_answerer(question=question, context=context)
