Mjölnir: Breaking the Shield of Perturbation-Protected Gradients via Adaptive Diffusion

AAAI 2025technical

Perturbation-based mechanisms, such as differential privacy, mitigate gradient leakage attacks by introducing noise into the gradients, thereby preventing attackers from reconstructing clients' private data from the leaked gradients. However, can gradient perturbation protection mechanisms truly def…

Graph Knows Unknowns: Reformulate Zero-Shot Learning as Sample-Level Graph Recognition

AAAI 2023technical

Zero-shot learning (ZSL) is an extreme case of transfer learning that aims to recognize samples (e.g., images) of unseen classes relying on a train-set covering only seen classes and a set of auxiliary knowledge (e.g., semantic descriptors). Existing methods usually resort to constructing a visual-t…
