+## ⚠️ Limitations
 
-Limitations
-The model is primarily trained on the SQuAD dataset and may not perform well on domain-specific question-answering tasks without additional fine-tuning. The model may struggle with highly ambiguous or multi-answer questions.

-Frequently Asked Questions (FAQ)
-
-Q: How can I fine-tune this model on a custom dataset?
-A: To fine-tune the model on your own dataset, you can follow these steps:1. Preprocess your dataset into a format compatible with the Hugging Face `Trainer`.2. Use the `RobertaForQuestionAnswering` class and set up the fine-tuning loop using the `Trainer` API from Hugging Face.3. Train the model on your dataset and evaluate it using metrics like F1 and Exact Match.
-Q: What if my model is running out of memory during inference?
-A: If you are running out of memory, try the following:
-- Use smaller batch sizes or batch the inference.
-- Perform inference on CPU if GPU memory is insufficient.
-- Quantize the model further (e.g., FP16 to INT8) to reduce the model size.
-Q: Can I use this model for other NLP tasks?
-A: This model is primarily fine-tuned for question answering. If you want to adapt it for other NLP tasks (such as sentiment analysis or text classification), you will need to modify the head of the model accordingly and fine-tune it on the relevant dataset.
