RoBERTa has almost similar architecture as compare to BERT, but in order to improve the results on BERT architecture, the authors made some simple design changes in its architecture and training procedure. These changes are:

The problem with the original implementation is the fact that chosen tokens for masking for a given text sequence across different batches are sometimes the same.

This article is being improved by another user right now. You can suggest the changes for now and it will be under the article's discussion tab.

Dynamically changing the masking pattern: In BERT architecture, the masking is performed once during data preprocessing, resulting in a single static mask. To avoid using the single static mask, training data is duplicated and masked 10 times, each time with a different mask strategy over 40 epochs thus having 4 epochs with the same mask.

Additionally, RoBERTa uses a dynamic masking technique during training that helps the model learn more robust and generalizable roberta pires representations of words.

model. Initializing with a config file does not load the weights associated with the model, only the configuration.

As a reminder, the BERT base model was trained on a batch size of 256 sequences for a million steps. The authors tried training BERT on batch sizes of 2K and 8K and the latter value was chosen for training RoBERTa.

Attentions weights after the attention softmax, used to compute the weighted average in the self-attention

Both individuals and organizations that work with arXivLabs have embraced and accepted our values of openness, community, excellence, and user data privacy. arXiv is committed to these values and only works with partners that adhere to them.
