Edit 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

This strategy is compared with dynamic masking in which different masking is generated  every time we pass data into the model.

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:

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.

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 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.

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

Thanks to the intuitive Fraunhofer graphical programming language NEPO, which is spoken in the “LAB“, simple and sophisticated programs can be created in pelo time at all. Like puzzle pieces, the NEPO programming blocks can be plugged together.
