TL;DR本文提出了一种基于低频领域的对抗攻击方法，能够有效地减少模型查询次数，即使模型和防御策略未知，也能规避图像转换的防御策略，并展示了使用该技术欺骗 Google Cloud Vision 平台模型查询次数极低的成果。
Abstract
adversarial images aim to change a target model's decision by minimally
perturbing a target image. In the black-box setting, the absence of gradient
information often renders this search problem costly in terms of query
complexity. In this paper we propose to restrict the search for ad
