Pegasus CNN/DailyMail (TensorFlow)

This is a TensorFlow version of the google/pegasus-cnn_dailymail model, converted from PyTorch weights.

Model Description

PEGASUS is a pre-training approach for abstractive text summarization. This model was fine-tuned on the CNN/DailyMail dataset for news summarization tasks.

Key Features:

• 🔄 Converted from PyTorch to TensorFlow for better TF.js and TensorFlow ecosystem compatibility
• 📰 Specialized for news article summarization
• 🎯 Fine-tuned on CNN/DailyMail dataset

Usage

from transformers import TFAutoModelForSeq2SeqLM, AutoTokenizer

# Load model and tokenizer
model = TFAutoModelForSeq2SeqLM.from_pretrained("your-username/pegasus-cnn-dailymail-tf")
tokenizer = AutoTokenizer.from_pretrained("your-username/pegasus-cnn-dailymail-tf")

# Example usage
article = "Your news article text here..."
inputs = tokenizer(article, max_length=1024, return_tensors="tf", truncation=True)
summary_ids = model.generate(inputs["input_ids"], max_length=150, min_length=30, length_penalty=2.0, num_beams=4, early_stopping=True)
summary = tokenizer.decode(summary_ids[0], skip_special_tokens=True)
print(summary)

Model Details

• Model Type: Sequence-to-sequence (Text Summarization)
• Language: English
• License: Apache 2.0
• Framework: TensorFlow
• Base Model: google/pegasus-cnn_dailymail

Training Data

This model was originally trained on the CNN/DailyMail dataset, which contains news articles paired with human-written summaries.

Performance

This TensorFlow model should perform identically to the original PyTorch version, as it was converted directly from the same weights.
