Model Card for Romanized Bengali Transliterator

Model Summary

This model is a Marian-based Seq2Seq transliterator trained on the Romanized Bengali dataset (975k pairs).
It maps Bengali written in the Roman alphabet (Banglish) into native Bengali script.

Architecture: MarianMT (Seq2Seq Transformer)
Parameters: ~60M
Training Data: romanized_bengali dataset (rule-based transliteration from Bengali Wikipedia)
Languages: Bengali (Romanized ↔ Bangla script)

Intended Use

Transliteration of Banglish into Bengali for:
- Social media analytics
- Search and information retrieval
- Chatbots and assistants
- Hate speech detection tasks

Example Usage

python

from transformers import MarianMTModel, MarianTokenizer

model_name = "sk-community/romanized_bengali_transliterator"
tokenizer = MarianTokenizer.from_pretrained(model_name)
model = MarianMTModel.from_pretrained(model_name)

input_text = "tumi kemon acho"
inputs = tokenizer(input_text, return_tensors="pt")
outputs = model.generate(**inputs)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
# Output: "তুমি কেমন আছো"

Performance

BLEU (Bengali): 77.82
CER: 0.16
WER: 0.25
