A pressure parametric dark energy modelJun 12 2018Jun 16 2018In this paper, we propose a new pressure parametric model of the total cosmos energy components in a spatially flat Friedmann-Robertson-Walker (FRW) universe and then reconstruct the model into quintessence and phantom scenarios, respectively. By constraining ... More
Symbolic relative entropy in quantifying nonlinear dynamics of equalities-involved heartbeatsJan 02 2018Jan 28 2019Symbolic relative entropy, an efficient nonlinear complexity parameter measuring probabilistic divergences of symbolic sequences, is proposed in our nonlinear dynamics analysis of heart rates considering equal states. Equalities are not rare in discrete ... More
Estimation of Treatment Effects for Heterogeneous Matched Pairs Data with Probit ModelsNov 07 2017Estimating the effect of medical treatments on subject responses is one of the crucial problems in medical research. Matched-pairs designs are commonly implemented in the field of medical research to eliminate confounding and improve efficiency. In this ... More
Efficient Mixed-Norm Regularization: Algorithms and Safe Screening MethodsJul 16 2013Sparse learning has recently received increasing attention in many areas including machine learning, statistics, and applied mathematics. The mixed-norm regularization based on the l1q norm with q>1 is attractive in many applications of regression and ... More
Curvatures at the singular points of algebraic curves and surfacesMay 18 2014In this paper, we study the computation of curvatures at the singular points of algebraic curves and surfaces. The idea is to convert the problem to compute the curvatures of the corresponding regular parametric curves and surfaces, which have intersections ... More
