A led-large-16384 model to summarize ArXiv papers. Inputs are the abstracts of papers and full documents, and outputs are the summaries of the papers.
As described in
Longformer: The Long-Document Transformer by Iz Beltagy, Matthew E. Peters, Arman Cohan,
led-base-16384 was initialized from
bart-base since both models share the exact same architecture. To
be able to process 16K tokens,
bart-base's position embedding matrix was simply copied 16 times.
