# English-Kannada NLLB Machine Translation Dataset

This dataset contains English-Kannada parallel text from NLLB dataset along with new NLLB model translations.

## Dataset Structure

- Train: 16,702 examples
- Test: 8,295 examples  
- Validation: 4,017 examples

### Features

- `en`: Source English text (from NLLB Dataset)
- `kn`: Human-translated Kannada text (from NLLB Dataset)
- `kn_nllb`: Machine-translated Kannada text using facebook/nllb-200-distilled-600M model

While `kn` translations are available in the NLLB dataset, their quality is poor. Therefore, we created `kn_nllb` by translating the English source text using NLLB's distilled model to obtain cleaner translations.

## Preprocessing

- Filtered: Minimum 5 words in both English and NLLB-translated Kannada texts
- Train-test split: 2:1 ratio

## Loading the Dataset

### Using Pandas
```python
import pandas as pd

splits = {
   'train': 'data/train-00000-of-00001.parquet',
   'validation': 'data/validation-00000-of-00001.parquet', 
   'test': 'data/test-00000-of-00001.parquet'
}

# Load all splits into DataFrames
dataframes = {}
for split, path in splits.items():
   dataframes[split] = pd.read_parquet(f"hf://datasets/pavan-naik/mt-nllb-en-kn/{path}")

# Access individual splits
train_data = dataframes['train']
test_data = dataframes['test']
validation_data = dataframes['validation']

```

### Using HuggingFace 🤗 Datasets
```python
from datasets import load_dataset

# Load from HuggingFace Hub
dataset = load_dataset("pavan-naik/mt-nllb-en-kn")

# Access splits
train_data = dataset["train"]
test_data = dataset["test"]
validation_data = dataset["validation"]

```
