Roberta base model trained on Azerbaijani subset of OSCAR corpus as a part of  [research](https://peerj.com/articles/cs-1974/)  on application of text augentation for low-resource languages. 
It was developed to enhance text classification tasks in Azerbaijani, a low-resource language in the NLP domain. The model was trained using the Azerbaijani subset of the OSCAR corpus and further fine-tuned on a labeled news dataset.


## Training Data
The model was pre-trained on the Azerbaijani subset of the OSCAR corpus, and fine-tuned on approximately 3 million sentences from Azertag News Agency covering diverse topics such as politics, economy, culture, sports, technology, and health.

## Usage
```python
from transformers import AutoTokenizer, AutoModelWithLMHead

tokenizer = AutoTokenizer.from_pretrained("iamdenay/roberta-azerbaijani")

model = AutoModelWithLMHead.from_pretrained("iamdenay/roberta-azerbaijani")
```
```python
from transformers import pipeline
model_mask = pipeline('fill-mask', model='iamdenay/roberta-azerbaijani')
model_mask("Le tweet <mask>.")
```

## Output
```python
[{'sequence': 'azərtac xəbər verir ki',
  'score': 0.9791,
  'token': 1053,
  'token_str': 'verir'},
 {'sequence': 'azərtac xəbər verib ki',
  'score': 0.0044,
  'token': 2313,
  'token_str': 'verib'},
 ... ]
```

## Limitations 

- Language Specificity: The model is trained exclusively on Azerbaijani and may not generalize well to other languages.
- Data Bias: The fine-tuning data is sourced from news articles, which may contain biases or specific journalistic styles.
- Agglutinative Language Challenges: Azerbaijani's agglutinative nature can lead to sparsity in the word space due to numerous morphological variations.

## Ethical Considerations
- Content Sensitivity: The dataset may include sensitive topics. Users should ensure compliance with ethical standards when deploying the model.
- Bias and Fairness: Be aware of potential biases in the training data that could affect model predictions.
