Howto train translation model WITHOUT VALIDATION data?
Hi,I trained a m2m100 model against technical / mechanical  corpus in 6 languages from existing translations texts .The training data will permit the model to understand the new words of this technical world.But unfortunately at this time I have no evaluation data.I will have evaluations data, only when using the trained model and translating new texts. A human will read these auto translated texts and will indicate if translation is right or not. (and so this may be my validation data)So, I have some questions :1/ how to evaluate blue score in this context ?2/ It is a bit complicated to knwo if I enough trained my models (how to adjust n_epochs ?)3/ What do you advice in my usecase ?
