BART Paraphrase Model (Large)

A large BART seq2seq (text2text generation) model fine-tuned on 3 paraphrase datasets.

Model description

The BART model was proposed in BART: Denoising Sequence-to-Sequence Pre-training for Natural Language Generation, Translation, and Comprehension by Lewis et al. (2019).

  • Bart uses a standard seq2seq/machine translation architecture with a bidirectional encoder (like BERT) and a left-to-right decoder (like GPT).
  • The pretraining task involves randomly shuffling the order of the original sentences and a novel in-filling scheme, where spans of text are replaced with a single mask token.
  • BART is particularly effective when fine tuned for text generation. This model is fine-tuned on 3 paraphrase datasets (Quora, PAWS and MSR paraphrase corpus).

The original BART code is from this repository.

Intended uses & limitations

You can use the pre-trained model for paraphrasing an input sentence.

How to use

import torch
from transformers import BartForConditionalGeneration, BartTokenizer

input_sentence = "They were there to enjoy us and they were there to pray for us."

model = BartForConditionalGeneration.from_pretrained('eugenesiow/bart-paraphrase')
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model = model.to(device)
tokenizer = BartTokenizer.from_pretrained('eugenesiow/bart-paraphrase')
batch = tokenizer(input_sentence, return_tensors='pt')
generated_ids = model.generate(batch['input_ids'])
generated_sentence = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)



['They were there to enjoy us and to pray for us.']

Training data

The model was fine-tuned on a pretrained facebook/bart-large, using the Quora, PAWS and MSR paraphrase corpus.

Training procedure

We follow the training procedure provided in the simpletransformers seq2seq example.
