CantonMT: Cantonese to English NMT Platform with Fine-Tuned Models Using
  Synthetic Back-Translation Data
Kung Yin Hong Lifeng Han Riza Batista-Navarro Goran Nenadic
Neural Machine Translation (NMT) for low-resource languages is still a
challenging task in front of NLP researchers. In this work, we deploy a
standard data augmentation methodology by back-translation to a new language
translation direction Cantonese-to-English. We present the models we fine-tuned
using the limited amount of real data and the synthetic data we generated using
back-translation including OpusMT, NLLB, and mBART. We carried out automatic
evaluation using a range of different metrics including lexical-based and
embedding-based. Furthermore. we create a user-friendly interface for the
models we included in this\textsc{ CantonMT} research project and make it
available to facilitate Cantonese-to-English MT research. Researchers can add
more models into this platform via our open-source\textsc{ CantonMT} toolkit
