model. Initializing with a config file does not load the weights associated with the model, only the configuration.
The problem with the original implementation is the fact that chosen tokens for masking for a given text sequence across different batches are sometimes the same.

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 conterraneo sentences into BERT input hurts the performance, compared to passing sequences consisting of several sentences. 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.
Roberta has been one of the most successful feminization names, up at #64 in 1936. It's a name that's found all over children's lit, often nicknamed Bobbie or Robbie, though Bertie is another possibility.
Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general

and, as we will show, hyperparameter choices have significant impact on the final results. We present a replication
This is useful if you want more control over how to convert input_ids indices into associated vectors
, 2019) that carefully measures the impact of many key hyperparameters and training data size. We find that BERT was significantly undertrained, and can match or exceed the performance of every model published after it. Our best model achieves state-of-the-art results on GLUE, RACE and SQuAD. These results highlight the importance of previously overlooked design choices, and raise questions about the source of recently reported improvements. We release our models and code. Subjects:
RoBERTa is pretrained on a combination of five massive datasets resulting in a Completa of 160 GB of text data. In comparison, BERT large is pretrained only on 13 Descubra GB of data. Finally, the authors increase the number of training steps from 100K to 500K.
