BigBird large model BigBird, is a sparse attention based transformer which extends Transformer based models, such as BERT to much longer sequences. Moreover, BigBird comes along with a theoretical understanding of the capabilities of a complete transformer that the sparse model can handle. It is a pretrained model on English language using a masked language modeling (MLM) objective. It was introduced in this paper and first released in this repository. Disclaimer: The team releasing BigBird did not write a model card for this model so this model card has been written by the Hugging Face team. Model description BigBird relies on block sparse attention instead of normal attention (i.e. BERT's attention) and can handle sequences up to a length of 4096 at a much lower compute cost compared to BERT. It has achieved SOTA on various tasks involving very long sequences such as long documents summarization, question answering with long contexts. How to use Here is how to use this model to get the features of a given text in PyTorch: Training Data This model is pre trained on four publicly available datasets: Books , CC News , Stories and Wikipedia . It used same sentencepiece vocabulary as…
