Almost Tight Multi-user Security Under Adaptive Corruptions

WebNoise-free GD and stochastic GD--corrupted by random noise--have been extensively studied in the literature, but less attention has been paid to an adversarial setting, that is subject to adversarial corruptions in the gradient values. In this work, we analyze the performance of GD under a proposed general adversarial framework.

WebJan 8, 2024 · Turning accidental adversaries into allies requires effort and tough conversations. But the alternative is continued deterioration. For example, in Linda’s and … WebIn this adversarial contamination model, our work addresses the following fundamental questions: • For an arbitrary truthful comparison graph G = (V;E ), what is the extent of adversarial corruption that can be tolerated up to which the true BTL parameters are uniquely identiﬁable? WebHowever, when data is instead affected by large (possibly adversarial) corruptions, these methods fail to converge, as corrupted data points draw iterates far from the true solution. A recently proposed solution to this is the quantileRK method, which avoids harmful corrupted data by exploring the space carefully as the method iterates. fda ind for biologics

Consequently, there is a need for methods that can perform certain tasks in statistics despite this difficulty. Webstable [23]. Introducing adversarial examples in the train-ing procedure can decrease neural networks sensitivity to these attacks [22]. Additional modules such as autoencoder [9], or GAN [26], have been used to protect neural networks from adversarial corruptions.
