    Modern cosmology has two competing theories of the origin of the universe: the "Singularity theory" and the "Superstring theory". Four Dilemmas of the "Super-string theory" are presented: the incompleteness of the eleven space–time dimensions,the inextricable dependence on the “Space–Time Background”, the "Zero-Brane the-ory" admitting stuff smaller than the Planck scale, and the pure mathematical theory that cannot be falsified by experiments. Although the "Singularity theory" is faced with many…Read more

  • Bézier Function Smooth Support Vector Regression
    with Q. Wu
    ICIC Express Letters, Part B: Applications 6 (7). 2015.
    Smooth function is the essence of the ε-smooth support vector regression (ε-SSVR) which is an unconstrained convex quadratic programming. In this paper, Bézier function as a new smooth function is proposed to replace the ε-insensitive loss function of ε-SSVR with tolerating a smaller error in fitting given data sets linearly and nonlinearly. The ε-Bézier function smooth support vector regression (ε-BSSVR) model is presented. Theoretical analyses show that the derived smooth function has improved…Read more

    Bezier Smooth Support Vector Classification
    with Q. Wu
    Journal of Computational Information Systems 11 (12). 2015.
    A new smooth method for solving the support vector machine classification (SVC) is presented. Since the objective function of the unconstrained SVC is non-smooth, we apply the smooth technique and replace the SVC function with Bézier function and get a class of Bézier smooth support vector machines (BSSVM). The fast Newton-Armijo algorithm is used to solve the BSSVM. Theoretical analysis and numerical results illustrate that this smooth SVM model improves in efficiency and accuracy compared with…Read more
  • Rotated Hyperbola Smooth Support Vector Regression
    with Q. Wu
    Journal of Computational Information Systems 11 (5). 2015.
    ε-support vector regression (ε-SVR) as a constrained minimization problem can be converted into an unconstrained convex quadratic programming. Smooth function is the essence of the ε-smooth support vector regression (ε-SSVR). In this paper, a new rotated hyperbola function is proposed to replace the ε-insensitive loss function. The ε-rotated hyperbola smooth support vector regression (ε-RHSSVR) model is presented. Theoretical analyses show that the derived smooth function has improved approximat…Read more
  • The transformation of Global sustainable information society in the age of global challenges
    with Wolfgang Hofkirchner
    Journal of Xi'an Jiaotong University 37 (1). 2017.
     全球性信息时代的到来, 对信息科学、 技术和社会等研究领域的全球合作提出了严峻的挑战。在 一个全球可持续信息社会的愿景中, 不同于当前人们利用技术、 环境等公共资源的主导方式, 它呼唤着科学 技术、 生态、 经济、 政治、 文化乃至社会整体系统对公共资源的合理性应用。与个人主义相反, 向全球可持续 信息社会的转型要求一种新的世界公民主义, 实现个体的反身性革命。社会进化是涌现的, 那么向全球可持 续信息社会的必要转变并非不可能。
  • Rotated hyperbola model for smooth support vector machine for classification
    Journal of China Universities of Posts and Telecommunications 25 (4). 2018.
    This article puts forward a novel smooth rotated hyperbola model for support vector machine (RHSSVM) for classification. As is well known, the Support vector machine (SVM) is based on Statistical Learning Theory and performs its high precision on data classification. However, the objective function is non-differentiable at the zero point. Therefore the fast algorithms cannot be used to train and test the SVM. To deal with it, the proposed method is based on the approximation property of the hype…Read more
  • Analysis the Importance of The Concept of "Objective Non-Reality" In The Development of Philosophy
    Multidisciplinary Digital Publishing Institute Proceedings 2017 (1). 2017.
    From the origin of ancient Greek philosophy to the philosophy of medieval ages, although it appeared the discussion of "nominalism" and "realism" in medieval times, the exploration of the concept of "objective but non-real" did not get further developed. From the view of the inherent integration of the unity of general rationality on science and philosophy, professor Wu Kun revived the concept of "objective but non-reality" and creatively developed his "philosophy of information" system. Because…Read more
  • A smooth rotated hyperbola model for support vector machine (SVM) is proposed. The method is based on the approximation property of the hyperbola to its asymptotic lines. The rotated hyperbola model has the least error on approximating the plus function when the angle between the two asymptotic lines is 135 degree. Experimental result shows that compared with other smooth methods, the rotated hyperbola function support vector machine (RHSSVM) reduces the compute time and can efficiently ha…Read more

  • Face recognition method based on multi-class classification of smooth support vector machine
    with En Wu Qing, Liang Bo, Wang Wan, Wang
    Journal of Computer Applications 35 (s1). 2015.
    A new three-order piecewise function was used to smoothen the model of Support Vector Machine( SVM) and a Third-order Piecewise Smooth SVM( TPSSVM) was proposed. By theory analyzing, approximation accuracy of the smooth function to the plus function is higher than that of the available. When dealing with the multi-class problem, a coding method of multi-class classification based on one-against-rest was proposed. Principal Component Analysis( PCA) was employed to extract the main features of fac…Read more
  • Spatialization of Time from the Perspective of Information Philosophy
    Multidisciplinary Digital Publishing Institute Proceedings 1 (5). 2020.
    The spatialization mechanism of time is one of the important ways to explore the essence of time. The theory of cognitive linguistics holds that metaphor and metonymy are two ways of spatialization of time concept. However, from the perspective of Information Philosophy, the above research only stays at the level of regenerative temporal and spatial information(concept), and does not trace back to the source of objective ontology to explain the spatialization process of time. According to the on…Read more
