# Multilingual Language Detection Model

## Model Description
This repository contains a multilingual language detection model based on the XLM-RoBERTa base architecture. The model is capable of distinguishing between 21 different languages including Arabic, Azerbaijani, Bulgarian, German, Greek, English, Spanish, French, Hindi, Italian, Japanese, Dutch, Polish, Portuguese, Russian, Swahili, Thai, Turkish, Urdu, Vietnamese, and Chinese.

## How to Use
You can use this model directly with a pipeline for text classification, or you can use it with the `transformers` library for more custom usage, as shown in the example below.

### Quick Start
First, install the transformers library if you haven't already:
```bash
pip install transformers
```

```python
from transformers import AutoModelForSequenceClassification, XLMRobertaTokenizer
import torch

# Load tokenizer and model
tokenizer = XLMRobertaTokenizer.from_pretrained("LocalDoc/language_detection")
model = AutoModelForSequenceClassification.from_pretrained("LocalDoc/language_detection")

# Prepare text
text = "Əlqasım oğulları vorzakondu"
encoded_input = tokenizer(text, return_tensors='pt', truncation=True, max_length=512)

# Prediction
model.eval()
with torch.no_grad():
    outputs = model(**encoded_input)

# Process the outputs
logits = outputs.logits
probabilities = torch.nn.functional.softmax(logits, dim=-1)
predicted_class_index = probabilities.argmax().item()
labels = ["az", "ar", "bg", "de", "el", "en", "es", "fr", "hi", "it", "ja", "nl", "pl", "pt", "ru", "sw", "th", "tr", "ur", "vi", "zh"]
predicted_label = labels[predicted_class_index]
print(f"Predicted Language: {predicted_label}")
```

## Language Label Information

The model outputs a label for each prediction, corresponding to one of the languages listed below. Each label is associated with a specific language code as detailed in the following table:

| Label | Language Code | Language Name |
|-------|---------------|---------------|
| 0     | az            | Azerbaijani   |
| 1     | ar            | Arabic        |
| 2     | bg            | Bulgarian     |
| 3     | de            | German        |
| 4     | el            | Greek         |
| 5     | en            | English       |
| 6     | es            | Spanish       |
| 7     | fr            | French        |
| 8     | hi            | Hindi         |
| 9     | it            | Italian       |
| 10    | ja            | Japanese      |
| 11    | nl            | Dutch         |
| 12    | pl            | Polish        |
| 13    | pt            | Portuguese    |
| 14    | ru            | Russian       |
| 15    | sw            | Swahili       |
| 16    | th            | Thai          |
| 17    | tr            | Turkish       |
| 18    | ur            | Urdu          |
| 19    | vi            | Vietnamese    |
| 20    | zh            | Chinese       |

This mapping is utilized to decode the model's predictions into understandable language names, facilitating the interpretation of results for further processing or analysis.
