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
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:

model. Initializing with a config file does not load the weights associated with the model, only the configuration.
The authors experimented with removing/adding of NSP loss to different versions and concluded that removing the NSP loss matches or slightly improves downstream task performance
Passing single natural sentences into BERT input hurts the performance, compared to passing sequences consisting of several sentences. Informações adicionais One of the most likely hypothesises explaining this phenomenon is the difficulty for a model to learn long-range dependencies only relying on single sentences.
It is also important to keep in mind that batch size increase results in easier parallelization through a special technique called “
Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general
Apart from it, RoBERTa applies all four described aspects above with the same architecture parameters as BERT large. The total number of parameters of RoBERTa is 355M.
Attentions weights after the attention softmax, used to compute the weighted average in the self-attention
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.
Attentions weights after the attention softmax, used to compute the weighted average in the self-attention heads.
If you choose this second option, there are three possibilities you can use to gather all the input Tensors
This is useful if you want more control over how to convert input_ids indices into associated vectors
