WAT 2022 Parallel Corpus Filtering Task NMT Training Scripts

This repository includes the NMT training scripts for the WAT 2022 parallel corpus filtering task. We strongly recommend you pull the latest scripts since they may be subject to change.

Requirements

We use the followings.

• NVIDIA Docker
• NVIDIA GPU with CUDA

ASPEC dev/test sets are also required for training.

Docker

We prepared the Docker container that was already installed the tools for training. Use the following commands to run. You might want to change some variables in docker_run.sh. ~/wat2022-filtering-corpus should be changed to the corpus directory, which you placed cleaned data and dev/test sets as explained in the next section. Note that you can change ~/wat2022-filtering to the path you want to store the experimental results. This will be connected to the container as /host_disk.

$ git clone https://github.com/MorinoseiMorizo/wat2022-filtering.git
$ cd wat2022-filtering
$ ./docker_build.sh
$ ./docker_run.sh

Prepare the data

First, you need to prepare the corpus. Please place and rename your cleaned corpus and ASPEC dev/test as follows:

▾ wat2022-filtering-corpus/
    aspec-je.dev.en
    aspec-je.dev.ja
    aspec-je.test.en
    aspec-je.test.ja
    train.en
    train.ja

Training the NMT model

./docker_run.sh will train the model and evaluate it.

Preprocessing and training details are written in preprocess.sh and train_model_big_*.sh, respectively. We expect to train the model on a single A100 GPU. If you use other GPUs, you may need to reduce GPU memory usage. In such a case, you can change --max-tokens to 5000, and --update-freq to 16.
