AI总结:

提出一种通用强化学习框架,通过最小畸变制作对抗攻击并生成定位掩码,在图像、视频和ECG信号分类中优于现有方法,提升了模型的鲁棒性与可解释性。

摘要:

我们提出了一种通用的强化学习(RL)框架,专门用于针对不同模型类型制作对抗攻击,涵盖ECG信号分析(1D)、图像分类(2D)和视频分类(3D)。该框架专注于识别敏感区域,并以最小畸变和多种畸变类型诱导误分类。这种新颖的RL方法在所有三种应用中均优于现有最先进方法,证明了其高效性。我们的RL方法生成了卓越的定位掩码,增强了图像分类和ECG分析模型的可解释性。对于ECG分析等应用,我们的平台为临床医生突出显示了关键的ECG片段,同时确保了对常见畸变的抵抗力。这一综合工具旨在通过对抗训练增强鲁棒性,并提升跨各种应用和数据类型的透明度。

英文摘要:

We present a generic Reinforcement Learning (RL) framework optimized for crafting adversarial attacks on different model types spanning from ECG signal analysis (1D), image classification (2D), and video classification (3D). The framework focuses on identifying sensitive regions and inducing misclassifications with minimal distortions and various distortion types. The novel RL method outperforms state-of-the-art methods for all three applications, proving its efficiency. Our RL approach produces superior localization masks, enhancing interpretability for image classification and ECG analysis models. For applications such as ECG analysis, our platform highlights critical ECG segments for clinicians while ensuring resilience against prevalent distortions. This comprehensive tool aims to bolster both resilience with adversarial training and transparency across varied applications and data types.
