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

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.

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

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

This is useful if you want more control over how to convert input_ids indices into associated vectors

sequence instead of per-token classification). It is the first token of the sequence when built with

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

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

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

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.
