Summary
In this chapter, we implement a machine translation application as an example of an encoder-decoder task. In particular, we build on pretrained encoder-decoder transformer models, which exist in the Hugging Face library for a wide variety of language pairs. We first show how to use one of these models out-of-the-box to perform translation for one of the language pairs it has been exposed to during pretraining: English to Romanian. Afterward, we fine-tune the model to a new language combination that is has not seen before: Romanian to English. In both use cases, we use the T5 encoder-decoder model, which has been pretrained for several tasks, including machine translation.
