Simultaneous NMT/MMT framework in PyTorch

This repository includes the codes, the experiment configurations and the scripts to prepare/download data for the Simultaneous Machine Translation with Visual Context paper presented at EMNLP 2020.

Note for RL-based codebase

Please visit the sim-mt repository for the implementation of our RL-based pipeline. Specifically, sim-mt provides codebase for the following papers:

• Julia Ive et al. (2021) - Exploiting Multimodal Reinforcement Learning for Simultaneous Machine Translation
• Julia Ive et al. (2021) - Exploring Supervised and Unsupervised Rewards in Machine Translation

Overview

pysimt is a PyTorch-based sequence-to-sequence framework that facilitates research in unimodal and multi-modal machine translation. The framework is especially geared towards a set of recent simultaneous MT approaches, including heuristics-based decoding and prefix-to-prefix training/decoding. Common metrics such as average proportion (AP), average lag (AL), and consecutive wait (CW) are provided through well-defined APIs as well.

Installation

The essential dependency of pysimt is torch>=1.7. The following command will create an appropriate Anaconda environment with pysimt installed within in editable mode.

conda env create -f environment.yml

Once the installation is done, run pysimt-install-extra command if you want to use METEOR as an evaluation metric.
