摘要: Image classification is vulnerable to adversarial attacks. This work investigates the robustness of Saak transform against attacks towards high performance image classification. We develop a complete system based on multi-stage transform. In domain, clean and images demonstrate different distributions at spectral dimensions. Selection dimensions every stage can be viewed as an automatic denoising process. Motivated by this observation, we carefully design strategies feature extraction, representation that increase robustness. The performances with well-known datasets are demonstrated extensive experimental evaluations.
