Researchers have introduced Quadratic Objective Perturbation (QOP) as a novel method for differential privacy in machine learning. Unlike Linear Objective Perturbation (LOP), which requires bounded gradients, QOP uses a random quadratic form to induce strong convexity and stability. This approach allows for privacy guarantees under weaker assumptions, even in the interpolation regime, and is compatible with approximate solutions. AI
