## facebook/bart-base model fine-tuned on CNN/DailyMail

This model was created using the [nn_pruning](https://github.com/huggingface/nn_pruning) python library: the linear layers contains **23%** of the original  weights.



The model contains **45%** of the original weights **overall** (the embeddings account for a significant part of the model, and they are not pruned by this method).

## Fine-Pruning details
This model was fine-tuned from the HuggingFace [model](https://huggingface.co/facebook/bart-base).
A side-effect of block pruning is that some of the attention heads are completely removed: 61 heads were removed on a total of 216 (28.2%).
