The goal of this task is to generate concise and meaningful summaries of long news articles using an Encoder–Decoder Transformer model, specifically T5 or BART.
This model performs abstractive summarization, meaning it rephrases and condenses content instead of just copying key sentences.
Dataset: CNN/DailyMail News Summarization Dataset
Each record includes:
- 📰 Article: Full news passage
- ✍️ Highlights: Human-written summary
The dataset is widely used for training summarization models in natural language processing.
To fine-tune a T5 Encoder–Decoder model for abstractive text summarization that:
- Compresses long-form text into concise summaries
- Retains key context and meaning
- Generates fluent, human-like summaries
- Architecture: T5 (Text-to-Text Transfer Transformer)
- Training Framework: Hugging Face Transformers
- Optimizer: AdamW
- Learning Rate: 5e-5
- Epochs: 1 (demo fine-tuning)
- Device: NVIDIA T4 GPU
- Dataset Subset: CNN/DailyMail
The model was fine-tuned to translate full-length news articles into meaningful, single-paragraph summaries.
| Metric | Value |
|---|---|
| Training Loss | 1.1381 |
| Validation Loss | 0.8295 |
| Device Used | NVIDIA T4 GPU |
| Epochs | 1 |
| Time Taken | ~1 minute |
| Model Output Directory | ./t5-summarizer/final_model |
Evaluation Metrics Used: ROUGE-1, ROUGE-2, ROUGE-L
| Metric | Score |
|---|---|
| ROUGE-1 | 31.54 |
| ROUGE-2 | 12.89 |
| ROUGE-L | 28.73 |
| ROUGE-Lsum | 28.75 |
These metrics show strong summarization performance given a short fine-tuning duration.

⭐ "Summarization is the art of transforming paragraphs into wisdom — where Transformers learn to read, think, and write like humans."
