查询词典 criterion

A new least-squares-based algorithm that introduces a within-class scatter with guaranteed classification performance in the design of least squares support vector machines is presented.This algorithm can obtain better correctness that reformulates primal LS-SVM problems with optimality criterion Min w′Mw where w is the weight vector corresponding the primal LS-SVM problems,M is the within-class scatter matrix.

提出了一个新的最小二乘支持向量机算法，该算法向最小二乘支持向量机优化模型中融入了类内散度思想，即用优化准则Min w′Mw对原LS-SVM进行重组合，w为对应LS-SVM中的权向量，M是类内散度矩阵。

The methods most in use to the solution of the problem with unacceptable frequency bands: one is a mathematical programming or optimum criterion method; the other is structure matrix perturbation.

前者的局限性是结构重分析次数多，计算时间长；后者虽可在一定程度上避免重分析，但其迭代步长难以确定。

In order to study the therapeutic effect of Sodium Hyaluronate injection of articular cavity and taking orally "JIN GU TONG XIAO WAN"(JGTXW, a TCM preparation for osteopathy disease) in the treatment of osteoarthritis of knee, 130 cases of OA were randomly divided into the treated group (66 cases, treated by SH and JGTXW) and control groups(64 cases, treated only by SH); The effect such as local pain, tumidness, joint movement and so on of the two groups in one year were observed and evaluated according to Lysholm criterion.

骨性关节炎是一种常见的老年退行性关节软骨病，随着我国人口的老年化增高，发病亦越来越多，严重影响老年人的生活质量，对膝关节骨性关节炎的治疗方法多，但疗效都均不太理想，不能阻止或延缓疾病的进展，近年来，以透明质酸制剂为代表的氨基糖类黏弹性物质补充疗法，在防治OA的基础研究和临床应用上取得了良好效果，为OA治疗寻找到了新的途径〔1〕。
