BanglaTranslator

Translate bangla to english. This model is train based on encoder decoder with attention mechanism. This repository may be a starting point to approaching bangla machine translation problem. If this repository helps others people who are working on bangla machine translation then it would be very greatfull for me.

Dataset

I use dataset provide in http://www.manythings.org/anki/ben-eng.zip . This dataset contain english bangla sentence pair in the following format,

I'm counting on you.	আমি আপনার উপর নির্ভর করে আছি।
I want your opinion.	আমি আপনার মতামত চাই।
How is your daughter?	আপনার মেয়ে কেমন আছে?

  • assets contain bangla font that used in plotting
  • data contain english bangla pair dataset
  • docs contrain documeantaion bangla unicode poins and it's char maping
  • models contrain saved tokenize and training checkpoints if you do training
  • translator is the core of the project that contrain all the required scripts for this project.
  • infer-example.ipynb An example notebook that shows how predict on single sentence using saved checkpoints
  • training-example.ipynb you can use this notebook to train bangla to english translator model

Dependency

python 3.7
tensorflow 2.x
matplotlib
sklearn
tqdm
jupyter notebook

Pre-train model

If you want to just test the model then you need to download pretrain model from from google drive link and extract training_checkpoints.zip file under models directory

Test result

I test pre-train model and got result like bellow.

  • If you want to test it yourself please check infer-example.ipynb and also download pre-train model
