Random Directional Attack for Fooling Deep Neural Networks

1 code implementation6 Aug 2019 Wenjian Luo, Chenwang Wu, Nan Zhou, Li Ni

Unfortunately, as the model is nonlinear in most cases, the addition of perturbations in the gradient direction does not necessarily increase loss.

Algorithmic Collusion in Cournot Duopoly Market: Evidence from Experimental Economics

no code implementations21 Feb 2018 Nan Zhou, Li Zhang, Shijian Li, Zhijian Wang

In application, we hope, the frameworks, the algorithm design as well as the experiment environment illustrated in this work, can be an incubator or a test bed for researchers and policymakers to handle the emerging algorithmic collusion.

Global and Local Structure Preserving Sparse Subspace Learning: An Iterative Approach to Unsupervised Feature Selection

no code implementations2 Jun 2015 Nan Zhou, Yangyang Xu, Hong Cheng, Jun Fang, Witold Pedrycz

In this paper, we propose a global and local structure preserving sparse subspace learning (GLoSS) model for unsupervised feature selection.
