 # BART (large-sized model) 
 
-BART model pre-trained on English language. It was introduced in the paper [BART: Denoising Sequence-to-Sequence Pre-training for Natural Language Generation, Translation, and Comprehension](https://arxiv.org/abs/1910.13461) by Lewis et al. and first released in [this repository](https://github.com/pytorch/fairseq/tree/master/examples/bart).

-Disclaimer: The team releasing BART did not write a model card for this model so this model card has been written by the Hugging Face team.

 ## Model description
 
 BART is a transformer encoder-decoder (seq2seq) model with a bidirectional (BERT-like) encoder and an autoregressive (GPT-like) decoder. BART is pre-trained by (1) corrupting text with an arbitrary noising function, and (2) learning a model to reconstruct the original text.
 
 BART is particularly effective when fine-tuned for text generation (e.g. summarization, translation) but also works well for comprehension tasks (e.g. text classification, question answering).
 
+Weights shared here are effectively from facebook/bart-large but with added noise for BOS embedding to assist the finetuning.

 ## Intended uses & limitations
 
 There have been quite a few issues related to finetuning BART for text generation, and this repo implements solution discussed in [#15559](https://github.com/huggingface/transformers/issues/15559).
