Model Card for t5_small Summarization Model

Model Details

• Model Architecture: T5 (Text-to-Text Transfer Transformer)
• Variant: t5-small
• Task: Text Summarization
• Framework: Hugging Face Transformers

Training Data

• Dataset: CNN/DailyMail
• Content: News articles and their summaries
• Size: Approximately 300,000 article-summary pairs

Training Procedure

• Fine-tuning method: Using Hugging Face Transformers library
• Hyperparameters:
  • Learning rate: 5e-5
  • Batch size: 8
  • Number of epochs: 3
• Optimizer: AdamW

How to Use

1. Install the Hugging Face Transformers library:

pip install transformers

2. Load the model:

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

tokenizer = AutoTokenizer.from_pretrained("t5-small")
model = AutoModelForSeq2SeqLM.from_pretrained("t5-small")

3. Generate a summary:

input_text = "Your input text here"
inputs = tokenizer("summarize: " + input_text, return_tensors="pt", max_length=512, truncation=True)
summary_ids = model.generate(inputs["input_ids"], max_length=150, min_length=40, length_penalty=2.0, num_beams=4, early_stopping=True)
summary = tokenizer.decode(summary_ids[0], skip_special_tokens=True)

Evaluation

• Metric: ROUGE scores (Recall-Oriented Understudy for Gisting Evaluation)
• Exact scores not available, but typically evaluated on:
  • ROUGE-1 (unigram overlap)
  • ROUGE-2 (bigram overlap)
  • ROUGE-L (longest common subsequence)

Limitations

• Performance may be lower compared to larger T5 variants
• Optimized for news article summarization, may not perform as well on other text types
• Limited to input sequences of 512 tokens
• Generated summaries may sometimes contain factual inaccuracies

Ethical Considerations

• May inherit biases present in the CNN/DailyMail dataset
• Not suitable for summarizing sensitive or critical information without human review
• Users should be aware of potential biases and inaccuracies in generated summaries
• Should not be used as a sole source of information for decision-making processes
