## Model description
DistilBERT fine-tuned on SQuAD 2.0 : Encoder-based Transformer Language model. DistilBERT is a compact and efficient version of BERT (Bidirectional Encoder Representations from Transformers).<br>
It employs a distillation process that transfers knowledge from a larger pretrained model (like BERT) to a smaller one. <br>
Suitable for Question-Answering tasks, predicts answer spans within the context provided.<br>
**Language model:** distilbert-base-uncased
**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
For Question-Answering -
```python
!pip install transformers
from transformers import pipeline
model_checkpoint = "IProject-10/distilbert-base-uncased-finetuned-squad2"
question_answerer = pipeline("question-answering", model=model_checkpoint)
context = """
🤗 Transformers is backed by the three most popular deep learning libraries — Jax, PyTorch and TensorFlow — with a seamless integration
between them. It's straightforward to train your models with one before loading them for inference with the other.
"""
question = "Which deep learning libraries back 🤗 Transformers?"
question_answerer(question=question, context=context)
```
