Domain Adaptation in Neural Machine Translation

Domain Adaptation is useful for specializing current generic Machine Translation models, mainly when the specialized corpus is too limited to train a separate model. Furthermore, Domain Adaptation techniques can be handy for low-resource languages that share vocabulary and structure with other rich-resource family languages.

As part of my Machine Translation research, I managed to achieve successful results in retraining Neural Machine Translation models for the purpose of Domain Adaptation using OpenNMT-py (the PyTorch version of OpenNMT). In this article, I am elaborating on the path I took and the achieved outcomes; hopefully, this will be useful for others.

GPU Options for Neural Machine Translation

GPU

In this article, I am exploring several GPU options I have either used myself or considered, for training my Neural Machine Translation models. As GPU machines are known for being expensive, the main factor I am concentrating on here is “cost”, which can be determined not only by machine rates, but also in light of other considerations such as technical specifications, and long-term vs. short-term commitments.

Stand-alone Executable Translator for OpenNMT

The question was: if I want to have a stand-alone version of OpenNMT that does not require any manual preparations or installations on the target machine, and does not connect to the Internet for Machine Translation, what are my options to achieve this?

Note that my current implementation depends on an OpenNMT Localhost REST API which is perfect for most cases, but not for the case when a client wants to be able to move the whole thing as one package without any prior (manual) preparation or installation of dependencies.

After some research, I finally managed to achieve progress using Python Tkinter, PyInstaller, NSIS and the PyTorch version of OpenNMT.
