TranslateKar - English to Konkani (& vice-versa) Language Translator

Developed by: Sajal Mandrekar and Shreya Deepak Pai

Dataset generated by: Atit Naik, Saylee Phadte, Sajal and Shreya

A Neural Machine Translator for Konkani to English Translations and vice-versa. It uses the Transformer architecture implemented using tensorflow and keras

Prerequisite
Test translations using the saved model
Example Translations
Evaluation: Bleu Score
Building BERT Vocabulary
Training model from scratch
Using Pretrained weights
Terms and Conditions of use

Prerequisite

Make sure your python version is between 3.8 to 3.11 (to prevent any dependency issues)
(Optional) Create a virtual environment:
- python3 -m venv .myenv
- source ./.myenv/bin/activate
Install the libraries using pip: python3 -m pip install -r requirements.txt

Test translations using the saved model

simply run : python3 run_saved_model.py

It opens up a prompt to let you select the model (English to Konkani or Konkani to English) or specify the path to the model. On successful loading of the model, you can enter an input and it returns the translated output.

Building vocabulary

This requires you to have a dataset! The code uses BERT tokenizer (Word-Piece tokenizer) to generated the vocabulary. Note that this is a very CPU/GPU intensive task and thus can take a lot of time depending on your system performance.
run : python3 building_vocabulary.py
specify the path of your dataset and the max size of the vocabulary
Generates the vocabulary adding .vocab extention to file name of the dataset

Training model from scratch

Prerequisites:
- A parallel corpus in two separate files
- Two separate vocabulary files for source and target languages
Modify the configuration file config.env to set the dataset paths, vocabulary, epochs and architecture (leave it to default if you want to use the BASE configurations)
train the model: python3 transformer_train.py config.env

Using Pretrained weights

open config.env file and modify the variables to specify your dataset file and model name/path (Example shown below):

# -----Configurations of the Transformer model----- #

# Model name
MODEL_NAME=TRANS_BASE_EK

## Path to training data of source language
CONTEXT_DATA_PATH=dataset/FULL_DATA.en

## Path to training data of target language
TARGET_DATA_PATH=dataset/FULL_DATA.gom

## Path to vocabulary of source language
CONTEXT_TOKEN_PATH=vocabulary/bert_en.vocab

## Path to vocabulary data of target language
TARGET_TOKEN_PATH=vocabulary/bert_gom.vocab

# Reloading weights from pretrained model (Comment out or leave empty or set to 'None' if not using)
WEIGHTS_PATH=trained_models/T_BASE_EK_07_07/checkpoints/best_model.weights.hdf5

Make sure that architecture variables like NUM_LAYERS,DFF, etc match the architecture of the pretrained model weights (specified in config.env inside the checkpoints directory)
Set the epochs using the epochs variable
To start training run: python3 transformer_train.py config.env
