A Mask-Based Adversarial Defense Scheme
Weizhen Xu, Chenyi Zhang, Fangzhen Zhao +1
Adversarial attacks hamper the functionality and accuracy of Deep Neural Networks (DNNs) by meddling with subtle perturbations to their inputs.In this work, we propose a new Mask-b…
Escape saddle points by a simple gradient-descent based algorithm
Chenyi Zhang, Tongyang Li
Escaping saddle points is a central research topic in nonconvex optimization. In this paper, we propose a simple gradient-based algorithm such that for a smooth function $f\colon\m…
A Uniform Framework for Anomaly Detection in Deep Neural Networks
Fangzhen Zhao, Chenyi Zhang, Naipeng Dong +2
Deep neural networks (DNN) can achieve high performance when applied to In-Distribution (ID) data which come from the same distribution as the training set. When presented with ano…
Quantum algorithms for escaping from saddle points
Chenyi Zhang, Jiaqi Leng, Tongyang Li
We initiate the study of quantum algorithms for escaping from saddle points with provable guarantee. Given a function , our quantum algorithm ou…
