The free platform can be used at any time and without installation effort by any device with a standard Net browser - regardless of whether it is used on a PC, Mac or tablet. This minimizes the technical and technical hurdles for both teachers and students.
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

The authors of the paper conducted research for finding an optimal way to model the next sentence prediction task. As Ver mais 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 Perfeito 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.
model. Initializing with a config file does not load the weights associated with the model, only the configuration.
dynamically changing the masking pattern applied to the training data. The authors also collect a large new dataset ($text CC-News $) of comparable size to other privately used datasets, to better control for training set size effects
