-Custom translation model provides translations for a specific language pair. The outcome of a successful training is a model. To train a custom model, three mutually exclusive document types are required: training, tuning, and testing. If only training data is provided when queuing a training, Custom translation automatically assembles tuning and testing data. It uses a random subset of sentences from your training documents, and exclude these sentences from the training data itself. A minimum of 10,000 parallel training sentences are required to train a full model.
