hindi-to-kurukh

🇮🇳 Hindi to Kurukh (Oraon) Translator

This is a state-of-the-art neural machine translation model for translating Hindi into the tribal language Kurukh (Oraon). It achieves a low validation loss of 1.41, indicating high fluency and grammatical accuracy for daily conversation.

📊 Model Details

• Model Architecture: Google mT5-small (Multilingual T5)
• Task: Machine Translation (Hindi → Kurukh)
• Script: Devanagari (For both Input and Output)
• Final Training Loss: 1.41
• Developer: Ankit Lakra

🚀 Live Demo

📚 Training Data

The dataset consists of ~10,000 parallel sentence pairs sourced from:

1. Literature & Prose: High-quality alignments from classic Kurukh literary works and stories.
2. Government Lexicons: Terminology from the SCERT and Bharatavani portals.
3. Manual Curation: Common conversational phrases cleaned and verified by community members.

⚙️ Training Procedure

The model was fine-tuned on a Google Colab T4 instance using the Adafactor optimizer to handle the specific convergence needs of the mT5 architecture.

• Optimizer: Adafactor (Relative step disabled, Scale parameter disabled)
• Batch Size: 16
• Learning Rate: 3e-4
• Epochs: 20
• Loss Function: Cross Entropy Loss (Final: 1.41)

⚠️ Limitations

• Dialects: Kurukh has multiple regional dialects (Jharkhand, Chhattisgarh, Odisha). This model primarily follows the standard Jharkhand dialect found in published literature.
• Complex Vocabulary: While it handles daily sentences well, highly technical or scientific Hindi words may not have direct Kurukh equivalents in the model's vocabulary.
