# 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 amount of processing time and memory required to assess the ROUGE metrics on the validation and test sets were not supported by Kaggle at this moment in time.

## 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.
