A graph-embedded deep feedforward network for disease outcome classification and feature selection using gene expression dataJan 18 2018Feb 12 2018Gene expression data represents a unique challenge in predictive model building, because of the small number of samples $(n)$ compared to the huge amount of features $(p)$. This "$n<<p$" property has hampered application of deep learning techniques for ... More
Saliency Based Control in Random Feature NetworksMar 21 2014Aug 07 2014The ability to rapidly focus attention and react to salient environmental features enables animals to move agiley through their habitats. To replicate this kind of high-performance control of movement in synthetic systems, we propose a new approach to ... More
Generative Adversarial Networks with Inverse Transformation UnitSep 27 2017In this paper we introduce a new structure to Generative Adversarial Networks by adding an inverse transformation unit behind the generator. We present two theorems to claim the convergence of the model, and two conjectures to nonideal situations when ... More
