longformer-base-8192
Longformer is a transformer model for long documents.
longformer-base-8192 is a BERT-like model started from the RoBERTa checkpoint and pretrained for MLM on long documents. It supports sequences of length up to 8,192.
Longformer uses a combination of a sliding window (local) attention and global attention. Global attention is user-configured based on the task to allow the model to learn task-specific representations.
Please refer to the examples in modeling_longformer.py and the paper for more details on how to set global attention.
