Autoencoding Transformers

RoBERTa is an extension of BERT with changes to the pretraining procedure. The modifications include:

  • training the model longer, with bigger batches, over more data
  • removing the next sentence prediction objective
  • training on longer sequences
  • dynamically changing the masking pattern applied to the training data. The authors also collect a large new dataset ($\text{CC-News}$) of comparable size to other privately used datasets, to better control for training set size effects
