## Model Description

<!-- Provide a longer summary of what this model is. -->

- **Model type:** Multi-class classifier on top of a transformer
- **Language(s) (NLP):** Spanish varieties: Argentinian (ar), Chilean (cl), Mexican (mx), Spanish (es), and the rest (mix)
- **License:** GPL-3.0
- **Finetuned from:** XLM-RoBERTa large
- **Preprocessing and tokenisation:** the same as XLM-RoBERTa 

We provide models for a 3-class (es, mx, mix), a 4-class (cl, es, mx, mix) and a 5-class problem (ar, cl, es, mx, mix). For each case, models with 3 different seeds and the versions with one and two splits of the training documents are included. 
See the documentation of [docTransformer](https://github.com/cristinae/docTransformer) for more detailed information.

## Use

Use the CEREAL classification models with [docTransformer](https://github.com/cristinae/docTransformer).


## Example Usage

Use these models for evaluation, classification or explanation using integrated gradients:

### Slurm 

#### Evaluation (gold label available)

```srun --ntasks 1 --gpus-per-task 1 python -u docClassifier.py --task evaluation -f trainedModel -o C4_cereal2splits_seed1.bin -b2 --sentence_batch_size 2 --split_documents True --test_dataset data/multivariant3all.test --plotConfusionFileName modelSplit2Seed3test.png```

#### Classification (gold label unavailable)

```srun --ntasks 1 --gpus-per-task 1 python -u docClassifier.py --task classification -f trainedModel -o C4_cereal2splits_seed1.bin -b1 --sentence_batch_size 2 --split_documents True --test_dataset ../es/es_meta_part_1.jsonl.unk```

#### Explanation

```srun --ntasks 1 --gpus-per-task 1 python -u docClassifier.py --task explanation -t data/testExample.mx -f trainedModel -o C4_cereal1split_seed1.bin -b1 --split_documents False  --xai_threshold_percentile 90```
