Researchers have introduced PRISM, a novel method for applying differential privacy to Low-Rank Adaptation (LoRA) in machine learning models. Traditional methods struggle because LoRA's low-rank factorization is not unique, leading to noise amplification. PRISM addresses this by being gauge-invariant, preventing bilinear noise amplification and allowing for stable privacy-utility trade-offs with bounded perturbations. The method also includes a DP-aware adaptive update rule to maintain numerical stability. AI
