# bart-base-News_Summarization_CNN

This model is a fine-tuned version of [facebook/bart-base](https://huggingface.co/facebook/bart-base).
It achieves the following results on the evaluation set:
- Loss: 0.1603

## Model description

## Intended uses & limitations

I used this to improve my skillset. I thank all of authors of the different technologies and dataset(s) for their contributions that have made this possible. 

Please make sure to properly cite the authors of the different technologies and dataset(s) as they absolutely deserve credit for their contributions.

## Training and evaluation data

Dataset Source: https://www.kaggle.com/datasets/hadasu92/cnn-articles-after-basic-cleaning

## Training procedure
CPU trained on all samples where the article length is less than 820 words and the summary length is no more than 52 words in length. Additionally, any sample that was missing a new article or summarization was removed. In all, 24,911 out of the possible 42,025 samples were used for training/testing/evaluation.
