	## Model description

	XLM-RoBERTa is a multilingual version of RoBERTa developed by Facebook AI. It is pre-trained on 2.5TB of filtered CommonCrawl data containing 100 languages.
	It is an extension of RoBERTa, which is itself a variant of the BERT model. XLM-RoBERTa is designed to handle multiple languages and demonstrate strong performance across a wide range of tasks, making it highly useful for multilingual natural language processing (NLP) applications.

	Language model: xlm-roberta-base
	Language: English
	Downstream-task: Question-Answering
	Training data: Train-set SQuAD 2.0
	Evaluation data: Evaluation-set SQuAD 2.0
	Hardware Accelerator used: GPU Tesla T4

	## Intended uses & limitations

	Multilingual Question-Answering

	For Question-Answering in English-

	```python
	!pip install transformers
	from transformers import pipeline
	model_checkpoint = "IProject-10/bert-base-uncased-finetuned-squad2"
	question_answerer = pipeline("question-answering", model=model_checkpoint)

	context = """
	The Statue of Unity is the world's tallest statue, with a height of 182 metres (597 feet), located near Kevadia in the state of Gujarat, India.
	"""

	question = "What is the height of statue of Unity?"
	question_answerer(question=question, context=context)
	```
	For Question-Answering in Hindi-

	```python
	!pip install transformers
	from transformers import pipeline
	model_checkpoint = "IProject-10/bert-base-uncased-finetuned-squad2"
	question_answerer = pipeline("question-answering", model=model_checkpoint)

	context = """
	स्टैच्यू ऑफ यूनिटी दुनिया की सबसे ऊंची प्रतिमा है, जिसकी ऊंचाई 182 मीटर (597 फीट) है, जो भारत के गुजरात राज्य में केवडिया के पास स्थित है।
	"""

	question = "स्टैच्यू ऑफ यूनिटी की ऊंचाई कितनी है?"
	question_answerer(question=question, context=context)
	```

	For Question-Answering in Spanish-

	```python
	!pip install transformers
	from transformers import pipeline
	model_checkpoint = "IProject-10/bert-base-uncased-finetuned-squad2"
	question_answerer = pipeline("question-answering", model=model_checkpoint)

	context = """
	La Estatua de la Unidad es la estatua más alta del mundo, con una altura de 182 metros (597 pies), ubicada cerca de Kevadia en el estado de Gujarat, India.
	"""

	question = "¿Cuál es la altura de la estatua de la Unidad?"
	question_answerer(question=question, context=context)
	```
