支持向量机泛化能力估计若干方法

计算机科学 2004年第8期31卷 125-126,F004页

作者：宋晓峰陈德钊胡上序南京航空航天大学生物医学工程系南京210016 浙江大学智能信息工程研究所杭州310027

支持向量机性能很大程度上依赖于其参数,为了确定最优参数,往往需要估计所建模型的泛化能力。本文详细介绍了目前国外支持向量机的各种泛化能力估计方法,分析了各种泛化能力估计方法的特点及其关系,并指出了今后的发展方向。

软件开发的复杂性决定了理想的软件可靠性模型既应具有包容众多复杂因素的能力,又要有构造灵活的功能。迄今为止,人们提出的众多模型,由于设定了很多近乎苛刻的条件,使它们难以具有普适性。Bayes网提供了解决这一问题的有力工具,论文就利用多重马尔可夫Bayes网建立起基于Bayes网的软件失效预测模型,并对此进行了详细的分析,给出了模型的求解步骤。最后,通过实例验证了该模型的有效性。

＜正＞Analogical to that for elastic plates as proposed by ***,the linear structural theories of multiferroic plates and shells are derived using the series expansion *** an orthogonal curvilinear coordinate system,the field of displacements is expanded in an infinite series of powers of the thickness-coordinate of the *** local coordinate of the thickness is introduced in the expansion of the fields of electric and magnetic potentials,which is different from the expansion of *** the variational principle,we obtain two-dimensional governing equations and the associated boundary conditions of the *** setting the Lame coefficients corresponding to the coordinates at the middle surface of the shell to unit,and the two principal radii of the middle surface of the shell to infinity,the shell theory can directly be degenerated into the plate theory.

＜正＞ To solve high heat flux cooling problems in array electronic equipments, a new type heat pipe cold plate are designed and developed. The newly-designed heat pipe cold plate is uniquely different from normal thermosyphon, in which the bottom and the top of 8 tube branches are connected with each other to gain more satisfactory temperature evenness on the cold plate. In this paper, based on previous experimental and theoretical studies, a set of mathematical models for numerically simulating vapor-liquid two-phase flow and heat transfer in the heat pipe cold plate is established. Two fluid model is employed to describe flow characteristics and phase coupling between vapor and liquid. Differential equations are solved by finite volume method and IPSA algorithm is employed to consider vapor-liquid coupling effect
