ccdv/lsg-bart-base-4096-pubmed
This model is a fine-tuned version of ccdv/lsg-bart-base-4096 on the scientific_papers pubmed dataset.
It achieves the following results on the test set:
| Length | Sparse Type | Block Size | Sparsity | Connexions | R1 | R2 | RL | RLsum |

Model description
The model relies on Local-Sparse-Global attention to handle long sequences:
The model has about ~145 millions parameters (6 encoder layers - 6 decoder layers).
The model is warm started from BART-base, converted to handle long sequences (encoder only) and fine tuned.
