# BETO (Spanish BERT) + Spanish SQuAD2.0 + distillation using 'bert-base-multilingual-cased' as teacher
This model is a fine-tuned on [SQuAD-es-v2.0](https://github.com/ccasimiro88/TranslateAlignRetrieve) and **distilled** version of [BETO](https://github.com/dccuchile/beto) for **Q&A**.
Distillation makes the model smaller, fasert, cheaper and lighter than [bert-base-spanish-wwm-cased-finetuned-spa-squad2-es](https://github.com/huggingface/transformers/blob/master/model_cards/mrm8488/bert-base-spanish-wwm-cased-finetuned-spa-squad2-es/README.md)
This model was fine-tuned on the same dataset but using **distillation** during the process as mentioned above (and one more train epoch).
The **teacher model** for the distillation was `bert-base-multilingual-cased`. It is the same teacher used for `distilbert-base-multilingual-cased` AKA [**DistilmBERT**](https://github.com/huggingface/transformers/tree/master/examples/distillation) (on average is twice as fast as **mBERT-base**).
## Details of the downstream task (Q&A) - Dataset
<details>
[SQuAD-es-v2.0](https://github.com/ccasimiro88/TranslateAlignRetrieve)
| Dataset | # Q&A |
| ----------------------- | ----- |
| SQuAD2.0 Train | 130 K |
| SQuAD2.0-es-v2.0 | 111 K |
| SQuAD2.0 Dev | 12 K |
| SQuAD-es-v2.0-small Dev | 69 K |
</details>
## Model training
The model was trained on a Tesla P100 GPU and 25GB of RAM with the following command:
```bash
!export SQUAD_DIR=/path/to/squad-v2_spanish \
&& python transformers/examples/distillation/run_squad_w_distillation.py \
--model_type bert \
--model_name_or_path dccuchile/bert-base-spanish-wwm-cased \
--teacher_type bert \
--teacher_name_or_path bert-base-multilingual-cased \
--do_train \
--do_eval \
--do_lower_case \
--train_file $SQUAD_DIR/train-v2.json \
--predict_file $SQUAD_DIR/dev-v2.json \
--per_gpu_train_batch_size 12 \
--learning_rate 3e-5 \
--num_train_epochs 3.0 \
--max_seq_length 384 \
--doc_stride 128 \
--output_dir /content/model_output \
--save_steps 5000 \
--threads 4 \
--version_2_with_negative
```
## Results:
| Metric | # Value |
| --------- | ----------- |
| **Exact** | **82.40**65 |
| **F1** | **90.50**36 |
```json
{
"exact": 82.40657784457096,

"HasAns_exact": 75.13413304253,

"NoAns_f1": 96.68550873586845,
"NoAns_total": 23352,
"best_exact": 82.40657784457096,
"best_exact_thresh": 0.0,
"best_f1": 90.50369643376902,
"best_f1_thresh": 0.0
}
```
## Comparison:
| Model | f1 score |
| :-------------------------------------------------------------: | :-------: |
| bert-base-spanish-wwm-cased-finetuned-spa-squad2-es | 86.07 |
| **distill**-bert-base-spanish-wwm-cased-finetuned-spa-squad2-es | **90.50** |
So, yes, this version is even more accurate.
