# ccdv/lsg-bart-base-4096-multinews |
|
|
|
This model is a fine-tuned version of [ccdv/lsg-bart-base-4096](https://huggingface.co/ccdv/lsg-bart-base-4096) on the [multi_news default](https://huggingface.co/datasets/multi_news) dataset. \ |
|
It achieves the following results on the test set: |

## 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. |
