Uploading Corpora and
Training Engines (for
More Advanced Users)
The five features of MutNMT
discussed here allow anyone
to open the " black box " of
NMT and get inside it. Those
who feel comfortable with it
and are prepared to do more
work can request " Expert "
status to be able to upload
new corpora and train
new engines. This is very
exciting, but also time- and
resource-consuming. There
are lots of multilingual
public corpora available in
different formats, including
TMX and parallel text files
(e.g., see the OPUS site in
the sidebar). And if you
have a good translation
memory with >100K units,
you could try to train an
engine on it.6
Corpora for a
given language pair can be

combined for training, for a
total of 500K sentence pairs.
In addition, you'll need
to create smaller separate
corpora (3-5K sentence
pairs) for " Validation " and
" Testing. " I suggest adding
one more for " Evaluation "
(500 sentence pairs).
Assuming these data don't
overlap with the training
set or among themselves,
you'll be fully equipped for
the entire process. In MT
research and development,
it's standard practice to
produce validation and
testing data by splitting
them off from the large
training corpus. But some
public corpora are highly
repetitive, so you would
need to ensure that there's
no overlap among the
resulting subsets, otherwise
you may get inflated scores
but poor quality. In any
case, the corpora must be
fully aligned, cleaned, and
otherwise pre-processed to
be used with MutNMT.
" Expert " users may
be further promoted to
" Admin " status if they
decide to use MutNMT
in teaching or otherwise
partner with MultiTraiNMT
in an official capacity. For
further tips, please read the
materials referenced in the
notes section and the sidebar
and watch very helpful
videos on the MultiTraiNMT
YouTube channel.
Unpacking the Black Box
The best way to learn MT is
to unpack its black box. It's
becoming increasingly
possible thanks to efforts
like MultiTraiNMT. Getting
under the hood of NMT is
very empowering!

to train commercial MT engines may have 100M+ sentence pairs.

MutNMT is based on JoeyNMT, an educational NMT framework with a simplistic architecture

But bear in mind that " Sharing " it will make it public. Even if you keep it in your individual
collection, it's a good idea to double check with the developers on the confidentiality of the
uploaded data.
