# Multilingual Neural Machine Translation (Project A3)

**Developed by:** Htut Ko Ko (st126010)

* 👉  **Live App** : [huggingface.co/spaces/shadowsilence/burmese-english-translator](https://huggingface.co/spaces/shadowsilence/burmese-english-translator)

This project implements high-quality machine translation systems for multiple languages (Burmese, Thai, Chinese, Vietnamese, Hindi, Nepali, Urdu, Tagalog, Kazakh, Bengali, German) to English using two approaches:

1. **Fine-Tuned NLLB-200**: State-of-the-art multilingual model tailored for high-quality translation across all supported languages.
2. **Transformer from Scratch**: Educational implementation to demonstrate understanding of NMT architecture.

## Experiments

### Attention Mechanisms (Burmese-English)

I compared **General (Dot Product)** and **Additive (Bahdanau)** attention mechanisms using a Seq2Seq GRU model.

| Attention Mechanism           | Training Loss   | Training PPL     | Validation Loss | Validation PPL    |
| ----------------------------- | --------------- | ---------------- | --------------- | ----------------- |
| General (Dot)                 | 4.819           | 123.868          | 6.662           | 782.166           |
| **Additive (Bahdanau)** | **4.447** | **85.368** | **6.440** | **626.673** |

**Observation:** Additive Attention achieved lower validation perplexity, indicating better performance.
