# MobileBERT + SQuAD (v1.1) 📱❓ |
|
|
|
[mobilebert-uncased](https://huggingface.co/google/mobilebert-uncased) fine-tuned on [SQUAD v2.0 dataset](https://rajpurkar.github.io/SQuAD-explorer/explore/v2.0/dev/) for **Q&A** downstream task. |
|
|
|
## Details of the downstream task (Q&A) - Model 🧠 |
|
|
|
**MobileBERT** is a thin version of *BERT_LARGE*, while equipped with bottleneck structures and a carefully designed balance between self-attentions and feed-forward networks. |
|
|
|
The checkpoint used here is the original MobileBert Optimized Uncased English: (uncased_L-24_H-128_B-512_A-4_F-4_OPT) checkpoint. |

## Details of the downstream task (Q&A) - Dataset 📚 |
|
|
|
**S**tanford **Q**uestion **A**nswering **D**ataset (SQuAD) is a reading comprehension dataset, consisting of questions posed by crowdworkers on a set of Wikipedia articles, where the answer to every question is a segment of text, or span, from the corresponding reading passage, or the question might be unanswerable. |
|
SQuAD v1.1 contains **100,000+** question-answer pairs on **500+** articles. |
|
|
|
## Model training 🏋️ |
|
|
|
The model was trained on a Tesla P100 GPU and 25GB of RAM with the following command: |
|
|
|
```bash |
|
python transformers/examples/question-answering/run_squad.py \ |
|
--model_type bert \ |
|
--model_name_or_path 'google/mobilebert-uncased' \ |
|
--do_eval \ |
|
--do_train \ |
|
--do_lower_case \ |
|
--train_file '/content/dataset/train-v1.1.json' \ |
|
--predict_file '/content/dataset/dev-v1.1.json' \ |
|
--per_gpu_train_batch_size 16 \ |
|
--learning_rate 3e-5 \ |
|
--num_train_epochs 5 \ |
|
--max_seq_length 384 \ |
|
--doc_stride 128 \ |
|
--output_dir '/content/output' \ |
|
--overwrite_output_dir \ |
|
--save_steps 1000 |
|
``` |
|
|
|
It is important to say that this models converges much faster than other ones. So, it is also cheap to fine-tune. |

### Model in action 🚀 |
|
|
|
Fast usage with **pipelines**: |
|
|
|
```python |
|
from transformers import pipeline |
|
QnA_pipeline = pipeline('question-answering', model='mrm8488/mobilebert-uncased-finetuned-squadv1') |
|
QnA_pipeline({ |
|
'context': 'A new strain of flu that has the potential to become a pandemic has been identified in China by scientists.', |
|
'question': 'Who did identified it ?' |
|
}) |
|
|
|
# Output: {'answer': 'scientists.', 'end': 106, 'score': 0.7885545492172241, 'start': 96} |
