If you choose this second option, there are three possibilities you can use to gather all the input Tensors

The original BERT uses a subword-level tokenization with the vocabulary size of 30K which is learned after input preprocessing and using several heuristics. RoBERTa uses bytes instead of unicode characters as the base for subwords and expands the vocabulary size up to 50K without any preprocessing or input tokenization.

The corresponding number of training steps and the learning rate value became respectively 31K and 1e-3.

Retrieves sequence ids from a token list that has no special tokens added. This method is called when adding

It is also important to keep in mind that batch size increase results in easier parallelization through a special technique called “

The authors of the paper conducted research for finding an optimal way to model the next sentence prediction task. As a consequence, they found several valuable insights:

It more beneficial to construct input sequences by sampling contiguous sentences from a single document rather than from multiple documents. Normally, sequences are always constructed from contiguous full sentences of a single document so that the total length is at most 512 tokens.

a dictionary with one or several input Tensors associated to the input names given in the docstring:

This results in 15M and 20M additional parameters for BERT base and BERT large models respectively. The introduced encoding version in RoBERTa demonstrates slightly worse results than before.

Overall, RoBERTa is a powerful and effective language model that has made significant contributions to the Explore field of NLP and has helped to drive progress in a wide range of applications.
