## Introduction

This model was initialized from [vinai/bartpho-word-base](https://huggingface.co/vinai/bartpho-word-base) and converted to [Allenai's Longformer Encoder-Decoder (LED)](https://github.com/allenai/longformer#longformer) based on [Longformer: The Long-Document Transformer](https://arxiv.org/pdf/2004.05150.pdf).

To be able to process 16K tokens, *bartpho-word-base*'s position embedding matrix was simply copied 16 times.

This model is especially interesting for long-range summarization and question answering.


## Fine-tuning for down-stream task

[This notebook](https://colab.research.google.com/drive/12LjJazBl7Gam0XBPy_y0CTOJZeZ34c2v?usp=sharing) shows how led model can effectively be fine-tuned on a downstream task.
