# Important Note:
`load_best_model_at_end` is not working properly (I specified `metric_for_best_model` on another training but it still does not work), but the training results still show a valid trend.

# DSPFirst-Finetuning-4

This model is a fine-tuned version of [ahotrod/electra_large_discriminator_squad2_512](https://huggingface.co/ahotrod/electra_large_discriminator_squad2_512) on a generated Questions and Answers dataset from the DSPFirst textbook based on the SQuAD 2.0 format.<br />
It achieves the following results on the evaluation set:
- Loss: 0.9028
- Exact: 66.9843
- F1: 74.2286

## More accurate metrics:

### Before fine-tuning:

```
  "exact": 57.006726457399104,
  "f1": 61.997705120754276
```

### After fine-tuning:

```
  "exact": 66.98430493273543,
  "f1": 74.2285867775556
```

# Dataset
A visualization of the dataset can be found [here](https://github.gatech.edu/pages/VIP-ITS/textbook_SQuAD_explore/explore/textbookv1.0/textbook/).<br />
The split between train and test is 70% and 30% respectively.
```
DatasetDict({
    train: Dataset({
        features: ['id', 'title', 'context', 'question', 'answers'],
        num_rows: 4160
    })
    test: Dataset({
        features: ['id', 'title', 'context', 'question', 'answers'],
        num_rows: 1784
    })
})
```

## Intended uses & limitations

This model is fine-tuned to answer questions from the DSPFirst textbook. I'm not really sure what I am doing so you should review before using it.<br />
Also, you should improve the Dataset either by using a **better generated questions and answers model** (currently using https://github.com/patil-suraj/question_generation) or perform **data augmentation** to increase dataset size.

## Training and evaluation data

- `batch_size` of 6 results in 14.82 GB VRAM
- Utilizes `gradient_accumulation_steps` to get total batch size to 514 (batch size should be at least 256)
- 4.52 GB RAM
- 30% of the total questions is dedicated for evaluating.

## Training procedure
- The model was trained from [Google Colab](https://colab.research.google.com/drive/1dJXNstk2NSenwzdtl9xA8AqjP4LL-Ks_?usp=sharing)
- Utilizes Tesla P100 16GB, took 6.3 hours to train
- `load_best_model_at_end` is enabled in TrainingArguments

The following hyperparameters were used during training:
- learning_rate: 2e-05
- train_batch_size: 6
- eval_batch_size: 6
- seed: 42
- gradient_accumulation_steps: 86
- total_train_batch_size: 516
- optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08
- lr_scheduler_type: linear
- num_epochs: 10

### Model hyperparameters

- hidden_dropout_prob: 0.36
- attention_probs_dropout_prob = 0.36
