Researchers discovered that privacy vulnerabilities in neural networks exist in only a small fraction of weights, but these same weights are critical for model performance. They developed a new approach that preserves privacy by rewinding and fine-tuning only these critical weights instead of retraining entire networks, maintaining utility while defending against membership inference attacks.
Researchers propose the Superficial Safety Alignment Hypothesis (SSAH), suggesting that AI safety alignment in large language models can be understood as a binary classification task of fulfilling or refusing user requests.
