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 次序最小優(yōu)化算法優(yōu)化標準的單一閾值容易錯判優(yōu)化條件,從而導致花費大量時間尋找第二個優(yōu)化樣本。
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 第一章簡單介紹了非線性最優(yōu)化問題以及l(fā)c~1優(yōu)化問題的產(chǎn)生與發(fā)展,并給出了lc~1優(yōu)化問題的最優(yōu)性條件。
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 本文在優(yōu)化標準中增沒上下界兩個閾值來判斷優(yōu)化條件,避免了原西安理工大學碩士學位論文算法單一鬧值判決的這個缺點,加快了訓練速度,提高了識別率。
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 本文還研究了基于升階譜的雜交應力元方法,建立了一系列p5的高階雜交應力單元列式,數(shù)值計算結果顯示采用正確的高斯積分,將使得本方法切實可行,同時兼有升階譜和雜交元的優(yōu)勢。
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,針對近幾年發(fā)展起來的集值優(yōu)化,基于clarke切錐利用epigraph建立了一類集值映射的epi-導數(shù)并討論它的一些性質(zhì),同時給出集值優(yōu)化的充分(或必要)的最優(yōu)性條件。
