Implementation of the paper "Extracting Training Data from Large Language Models"(Carlini et al, 2020)

How to Run

1. (Optional) Change model type and hyperparameters at config.yaml
2. Text sampling from the victim language model
   • Run python inference.py for single-gpu generation from the victim language model.
   • Run python parallel_inference.py for faster generation from the victim language model.
3. Run python rerank.py to retrieve possibly memorized text sequence candidates

Contribution

• Prevents oversampling during the prefix selection
• Speeds up the inference with parallel Multi-GPU usage (only for gpt2-large)
• Clears up GPU VRAM memory usage after the corresponding task
• Rules out 'low-quality repeated generations' with repetition penalty and with ngram restriction
• Supports T5 Encoder-Decoder as the victim model
• Speeds up the reranking with parallel Multi-GPU usage
