The sequential minimal optimization algorithm optimizes the standard single threshold error tolerance optimization condition, thus results in the time-consume to seek the second optimization sample 次序最小优化算法优化标准的单一阈值容易错判优化条件,从而导致花费大量时间寻找第二个优化样本。
This paper is organized as follows : in the first chapter, we briefly review the origin and development of the nonlinear optimization problems and lc1 optimization problems, and the optimization conditions were presented 第一章简单介绍了非线性最优化问题以及lc~1优化问题的产生与发展,并给出了lc~1优化问题的最优性条件。
In this thesis, two thresholds, upper and lower are added to judge the optimization conditions . this avoided the original disadvantage, accelerated the training rate and improved identification rates 本文在优化标准中增没上下界两个阈值来判断优化条件,避免了原西安理工大学硕士学位论文算法单一闹值判决的这个缺点,加快了训练速度,提高了识别率。
After that in chapter four, a axisymmetric hybrid stress finite element for piezoelectric media is presented on the optimization condition for the coupling of electrical and elasticity . it's practicable and rational in the numerical example . in the fifth chapter, we study the p-version hybrid stress fem 本文还研究了基于升阶谱的杂交应力元方法,建立了一系列p5的高阶杂交应力单元列式,数值计算结果显示采用正确的高斯积分,将使得本方法切实可行,同时兼有升阶谱和杂交元的优势。
In recent years, set-valued optimization make much progress . in chapter 5, based on clarke tangent cone, we establish epiderivative of a class of set-valued maps and its properties . and furthermore, sufficiency ( or neccessity ) optimization conditions of set-valued optimization are also obtained 在第5章中,针对近几年发展起来的集值优化,基于clarke切锥利用epigraph建立了一类集值映射的epi-导数并讨论它的一些性质,同时给出集值优化的充分(或必要)的最优性条件。
