摘要:
深度学习的发明,使得人工智能技术迎来了新的机遇,再次进入了蓬勃发展期。其涉及到的隐私、安全、伦理等问题也日益受到了人们的广泛关注。以对抗样本生成为代表的新技术,直接将人工智能、特别是深度学习模型的脆弱性展示到了人们面前,使得人工智能技术在应用落地时,必须要重视此类问题。本文通过对抗样本生成技术的回顾,从信号层、内容层以及语义层三个层面,白盒攻击与黑盒攻击两个角度,简要介绍了对抗样本生成技术,目的是希望读者能够更好地发现对抗样本的本质,对机器学习模型的健壮性、安全性和可解释性研究有所启发。

Abstract:
With the invention of deep learning, artificial intelligence (AI) has ushered in new opportunities and is booming again. However, its privacy, security, ethics and other issues involved are also increasingly concerned by people. The adversarial samples, the vulnerability of artificial intelligence, especially deep learning models, are directly in front of us in recent years, which makes it necessary to pay attention to such problems during the practical application of AI technology. In this paper, a brief review of adversarial sample generation under white-box and black-box attack protocols is given. We summarize related techniques into three levels:signal level, content level and semantic level. We hope this paper can help readers better find the nature of the adversarial sample, which may improve the robustness, security and interpretability of the learned model.
