 BigBird, is a sparse-attention based transformer which extends Transformer based models, such as BERT to much longer sequences.
 
-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.

 Model is warm started from Korean BERT’s checkpoint.
