Exploring the Adversarial Frontier: Quantifying Robustness via Adversarial Hypervolume

no code implementations8 Mar 2024 Ping Guo, Cheng Gong, Xi Lin, Zhiyuan Yang, Qingfu Zhang

To address this gap, we propose a new metric termed adversarial hypervolume, assessing the robustness of deep learning models comprehensively over a range of perturbation intensities from a multi-objective optimization standpoint.

PuriDefense: Randomized Local Implicit Adversarial Purification for Defending Black-box Query-based Attacks

no code implementations19 Jan 2024 Ping Guo, Zhiyuan Yang, Xi Lin, Qingchuan Zhao, Qingfu Zhang

Black-box query-based attacks constitute significant threats to Machine Learning as a Service (MLaaS) systems since they can generate adversarial examples without accessing the target model's architecture and parameters.

Reducing Spatial Fitting Error in Distillation of Denoising Diffusion Models

1 code implementation7 Nov 2023 Shengzhe Zhou, Zejian Lee, Shengyuan Zhang, Lefan Hou, Changyuan Yang, Guang Yang, Zhiyuan Yang, Lingyun Sun

Based on our analysis with bias-variance decomposition and experimental observations, we attribute the degradation to the spatial fitting error occurring in the training of both the teacher and student model.
