# pegasus-finetuned-samsum

This model is a fine-tuned version of [google/pegasus-cnn_dailymail](https://huggingface.co/google/pegasus-cnn_dailymail) on the samsum dataset.
It achieves the following results on the evaluation set:
- Loss: 1.4245
- Rouge-1: 0.4403
- Rouge-2: 0.2102
- Rouge-L: 0.3491
- Rouge-Lsum: 0.3493

## Model description

This would be the 10th best-performing model on the [Papers with Code SAMsum leaderboard](https://paperswithcode.com/sota/text-summarization-on-samsum-corpus),
as of April 8, 2025.

## Intended uses & limitations

This model is designed for abstractive dialogue summarization. It can take in multi-turn conversations and generate concise summaries.

## How to Use

```Python
from transformers import pipeline

# Load summarization pipeline
model_name = "avanishd/pegasus-finetuned-samsum/"
summarizer = pipeline("summarization", model=model_name, tokenizer=model_name)

# Sample conversation
dialogue = """
John: Hey, are you free tomorrow?
Alice: I think so, why?
John: Want to catch a movie or grab lunch?
Alice: Sure, lunch sounds good. What time?
John: Let's say 1 PM at the new place downtown?
Alice: Works for me!
"""

# Generate summary
summary = summarizer(dialogue, max_length=60, min_length=15, do_sample=False)[0]['summary_text']

print("Summary:", summary)

```
