New TsallisPGD attack method improves adversarial attacks on semantic segmentation models

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 2 sources

Researchers have developed TsallisPGD, a novel adversarial attack method designed to more effectively target semantic segmentation models. This new approach utilizes Tsallis cross-entropy, a generalized form of standard cross-entropy, to adaptively adjust gradient weighting across pixels. Experiments on datasets like Cityscapes and Pascal VOC demonstrate that TsallisPGD outperforms existing methods in reducing model accuracy and mean intersection over union (mIoU). AI

    TsallisPGD: Adaptive Gradient Weighting for Adversarial Attacks on Semantic Segmentation

    Attacking semantic segmentation models is significantly harder than image classification models because an attacker must flip thousands of pixel predictions simultaneously. Standard pixel-wise cross-entropy (CE) is ill-suited to this setting: it tends to overemphasize already-mis…
