Lsg Bart Base 4096 Multinews

🚀 ccdv/lsg-bart-base-4096-multinews

This model is a fine - tuned version for text summarization, achieving good results on the multi_news dataset.

🚀 Quick Start

Note:

• Transformers >= 4.36.1
• This model relies on a custom modeling file, you need to add trust_remote_code=True
• See #13467

LSG ArXiv paper.
Github/conversion script is available at this link.

💻 Usage Examples

Basic Usage

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM, pipeline

tokenizer = AutoTokenizer.from_pretrained("ccdv/lsg-bart-base-4096-multinews", trust_remote_code=True)
model = AutoModelForSeq2SeqLM.from_pretrained("ccdv/lsg-bart-base-4096-multinews", trust_remote_code=True)

text = "Replace by what you want."
pipe = pipeline("text2text-generation", model=model, tokenizer=tokenizer, device=0)
generated_text = pipe(
  text, 
  truncation=True, 
  max_length=64, 
  no_repeat_ngram_size=7,
  num_beams=2,
  early_stopping=True
  )

✨ Features

Test Results with Smaller Block Size (Lower Resources)

📚 Documentation

Model description

The model relies on Local - Sparse - Global attention to handle long sequences:

The model has about ~145 millions parameters (6 encoder layers - 6 decoder layers).
The model is warm started from BART - base, converted to handle long sequences (encoder only) and fine tuned.
