Witches' Brew: Industrial Scale Data Poisoning via Gradient Matching [PDF]
arXiv, 2020 Data Poisoning attacks modify training data to maliciously control a model trained on such data. In this work, we focus on targeted poisoning attacks which cause a reclassification of an unmodified test image and as such breach model integrity. We consider a particularly malicious poisoning attack that is both "from scratch" and "clean label", meaning ...

Explore the Effect of Data Selection on Poison Efficiency in Backdoor Attacks [PDF]
arXiv, 2023 As the number of parameters in Deep Neural Networks (DNNs) scales, the thirst for training data also increases. To save costs, it has become common for users and enterprises to delegate time-consuming data collection to third parties. Unfortunately, recent research has shown that this practice raises the risk of DNNs being exposed to backdoor attacks ...

Poisoned classifiers are not only backdoored, they are fundamentally broken [PDF]
arXiv, 2020 Under a commonly-studied backdoor poisoning attack against classification models, an attacker adds a small trigger to a subset of the training data, such that the presence of this trigger at test time causes the classifier to always predict some target class.

Advanced Healthcare Materials, EarlyView.Schematic illustration of the mechanism of targeted delivery of nanoparticles including 1) paracellular, 2) endolysosomal escape, 3) receptor mediated endocytosis, and 4) M cell mediated transport for non‐GI diseases by oral administration such as atherosclerosis, cancer, diabetes, and brain diseases. Abstract Oral drug delivery is a promising approach

Data Poisoning Attacks on Regression Learning and Corresponding Defenses [PDF]
arXiv, 2020 Adversarial data poisoning is an effective attack against machine learning and threatens model integrity by introducing poisoned data into the training dataset. So far, it has been studied mostly for classification, even though regression learning is used in many mission critical systems (such as dosage of medication, control of cyber-physical systems ...

Parity effect in superconducting aluminum single electron transistors with spatial gap profile controlled by film thickness [PDF]
, 2006 We propose a novel method for suppression of quasiparticle poisoning in Al Coulomb blockade devices. The method is based on creation of a proper energy gap profile along the device. In contrast to the previously used techniques, the energy gap is controlled by the film thickness.

Propofol as a controlled substance: poison or remedy [PDF]
Korean Journal of Anesthesiology, 2015 Korea is the first, and perhaps only, country to classify propofol as a controlled substance. In February 2011, the Korean Ministry of Food and Drug Safety classified propofol as a psychotropic drug, making it illegal to prescribe or consume other than for stipulated treatments that may need sedation, such as a gastrointestinal endoscopy [1].
