architecture. Instantiating a configuration with the defaults will yield a similar configuration to that of
Nevertheless, in the vocabulary size growth in RoBERTa allows to encode almost any word or subword without using the unknown token, compared to BERT. This gives a considerable advantage to RoBERTa as the model can now more fully understand complex texts containing rare words.
This strategy is compared with dynamic masking in which different masking is generated every time we pass data into the model.

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

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 Perfeito length is at most 512 tokens.

The problem arises when we reach the end of a document. In this aspect, researchers compared whether it was worth stopping sampling sentences for such sequences Veja mais or additionally sampling the first several sentences of the next document (and adding a corresponding separator token between documents). The results showed that the first option is better.
