Detecting Backdoor Poisoning Attacks on Deep Neural Networks by Heatmap Clustering [PDF]
arXiv, 2022 Predicitions made by neural networks can be fraudulently altered by so-called poisoning attacks. A special case are backdoor poisoning attacks. We study suitable detection methods and introduce a new method called Heatmap Clustering. There, we apply a $k$-means clustering algorithm on heatmaps produced by the state-of-the-art explainable AI method ...

FRIB: Low-poisoning Rate Invisible Backdoor Attack based on Feature Repair [PDF]
arXiv, 2022 During the generation of invisible backdoor attack poisoned data, the feature space transformation operation tends to cause the loss of some poisoned features and weakens the mapping relationship between source images with triggers and target labels, resulting in the need for a higher poisoning rate to achieve the corresponding backdoor attack success ...

A promising poison information centre model for Africa
African Journal of Emergency Medicine, 2016 The burden of poisoning exposures in Africa is a significant public health concern, yet only ten African countries have poisons information centres. The establishment of poisons centres was subsequently identified as a priority.

Absolutely continuous copulas with prescribed support constructed by differential equations, with an application in toxicology [PDF]
arXiv, 2019 A new method for constructing absolutely continuous two--dimensional copulas by differential equations is presented. The copulas are symmetric with respect to reflection in the opposite diagonal. The support of the copula density may be prescribed to arbitrary opposite symmetric hypographs of invertible functions, containing the diagonal. The method is

Exploring the Limits of Model-Targeted Indiscriminate Data Poisoning Attacks [PDF]
arXiv, 2023 Indiscriminate data poisoning attacks aim to decrease a model's test accuracy by injecting a small amount of corrupted training data. Despite significant interest, existing attacks remain relatively ineffective against modern machine learning (ML) architectures.
