We have used some of these posts to build our list of alternatives and similar projects. As an example, we use the WikiText-103 dataset to pretrain the RoBERTa model following this tutorial.The pipeline and configurations in this document will work for other models supported by Fairseq, such as sequence-to-sequence machine translation models. Specifically, it follows FairSeq's tutorial, pretraining the model on the public wikitext-103 dataset. The Transformer is a Neural Machine Translation (NMT) model which uses attention mechanism to boost training speed and overall accuracy. To do so, it leverages message passing semantics allowing each process to communicate data to any of the other processes. RaySGD is a lightweight library for distributed deep learning, providing thin wrappers around PyTorch and TensorFlow native modules for data parallel training.
