Poison as a Cure: Detecting & Neutralizing Variable-Sized Backdoor Attacks in Deep Neural Networks [PDF]
arXiv, 2019 Deep learning models have recently shown to be vulnerable to backdoor poisoning, an insidious attack where the victim model predicts clean images correctly but classifies the same images as the target class when a trigger poison pattern is added. This poison pattern can be embedded in the training dataset by the adversary.

From Trojan Horses to Castle Walls: Unveiling Bilateral Data Poisoning Effects in Diffusion Models [PDF]
arXiv, 2023 While state-of-the-art diffusion models (DMs) excel in image generation, concerns regarding their security persist. Earlier research highlighted DMs' vulnerability to data poisoning attacks, but these studies placed stricter requirements than conventional methods like `BadNets' in image classification. This is because the art necessitates modifications

Advanced Science, EarlyView.YxMnyOx+2y catalyst provides dual active sites of Lewis acid (Y3+) and Mn for the co‐adsorption of H2O and O3, and the fast dissociation of adsorbed H2O to surface *OH. Then, a newly OH‐accompanied pathway for O3 decomposition is formed, transforming H2O to active ·OH radical, with the assistance of high energy electrons in the plasma.
