这些特性使扩散模型成为生成对抗净化的理想候选者。 因此,作者提出了一种新的对抗净化方法,称为DiffPure,给定一个预先训练的扩散模型,我们的方法包括两个步骤: 我们首先通过较小扩散时间步长的前向过程向对抗样本添加噪声; 然后求解逆随机微分方程(SDE)以从扩散的对抗样本中恢复干净的图像 。 该方法中的一个重要设计...
diffpure代码 哇塞,DiffPure代码可是个很有意思的存在!下面就来好好讲讲它。 一、DiffPure代码整体架构。 DiffPure代码主要围绕着图像去噪这一核心任务构建。它的整体架构设计旨在通过深度学习的方法,从噪声图像中恢复出清晰的原始图像。代码通常包含多个关键模块,这些模块相互协作,共同完成图像去噪的任务。 二、数据...
In this work, we propose DiffPure that uses diffusion models for adversarial purification: Given an adversarial example, we first diffuse it with a small amount of noise following a forward diffusion process, and then recover the clean image through a reverse generative process. To evaluate our ...
内容介绍中文摘要:扩散模型是有效的纯化方法,在现有分类器执行分类任务之前,使用生成方法去除噪声或对抗性攻击。然而,扩散模型的效率仍然是一个问题,现有的解决方案基于知识蒸馏,由于生成步骤较少,可能会危及生成质量。因此,我们提出Tendif...
we propose TendiffPure as a tensorized and compressed diffusion model for purification.Unlike the knowledge distillation methods,we directly compress U-Nets as backbones of diffusion models using tensor-train decomposition,which reduces the number of parameters and captures more spatial information in ...
