Когда несколько пикселей решают всё: One Pixel атака и способы защиты от неё

Удивительно, но факт: несколько изменений в изображении могут полностью поменять вывод нейросети, что ломает заложенную разработчиком логику. В данной статье мы не просто подсветим факт существования One Pixel атаки, но и комплексно разберём архитектурные факторы, которые влияют на устойчивость CV-систем к данному семейству атак.

Studying classical #CNN architectures such as #VGG and #ResNet, we observed that they could be sensitive to simple rotations... and that incorporating a biologically inspired retinotopic mapping could alleviate this and also bring other nice features observed in the human visual system.

Hear Jean-Nicolas Jérémie aka @jnjer present these results today at the 32nd International Conference on Artificial Neural Networks (#ICANN 2023) in Heraklion, Greece.

The figure below shows the accuracy of different CNNs to the task "is there an animal in the image" - with a classical (Linear) or retinotopic (polar) mapping. Note that VGG may answer confidently the wrong answer for images rotated around 160°...

#Resnet (pronounced re-snet) verb: to reset ones internet, or to switch ones modem on and off again. This can also be done in #Australia as a form of #protest against #dataRetention laws whereby IPs assigned to users must be stored from two years.

By using automated #resnetting methods #protestor were able to overload the #dataRetention system.
