# led-base-16384-finetuned-govreport |
|
|
|
This model is a fine-tuned version of [allenai/led-base-16384](https://huggingface.co/allenai/led-base-16384) on the [pszemraj/govreport-summarization-8192](https://huggingface.co/datasets/pszemraj/govreport-summarization-8192) dataset. |
|
It achieves the following results on the evaluation set: |
|
- Loss: 1.2887 |
|
|
|
The rouge metrics calculations were processed later down the line (final notebook can be found [HERE](https://www.kaggle.com/code/marcoloureno/led-base-16384-finetuned-govreport-metrics/notebook)). |
|
|
|
It achieved the following results on the validation set: |
|
- Rouge1: 50.3574 |
|
- Rouge2: 20.0448 |
|
- Rougel: 22.2156 |
|
- Rougelsum: 22.2156 |
|
|
|
It achieved the following results on the test set: |
|
- Rouge1: 52.6378 |
|
- Rouge2: 22.2130 |
|
- Rougel: 23.5898 |

## Model description |
|
|
|
As described in [Longformer: The Long-Document Transformer](https://arxiv.org/pdf/2004.05150.pdf) by Iz Beltagy, Matthew E. Peters, Arman Cohan, [Allenai's Longformer Encoder-Decoder (LED)](https://github.com/allenai/longformer#longformer) was initialized from [*bart-base*](https://huggingface.co/facebook/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. |
|
|
|
This model is especially interesting for long-range summarization and question answering. |
|
|
|
## Intended uses & limitations |
|
|
|
[pszemraj/govreport-summarization-8192](https://huggingface.co/datasets/pszemraj/govreport-summarization-8192) is a pre-processed version of the dataset [ccdv/govreport-summarization](https://huggingface.co/datasets/ccdv/govreport-summarization), which is a dataset for summarization of long documents adapted from this [repository](https://github.com/luyang-huang96/LongDocSum) and this [paper](https://arxiv.org/pdf/2104.02112.pdf). |
|
|
|
The Allenai's LED model was fine-tuned to this dataset, allowing the summarization of documents up to 16384 tokens. |
