threshold parameter造句
例句與造句
- Then , on the basis of coupled wave equations , theoretically studies of opo threshold parameters and of the conversion efficiency and of linewidth control are presented . several principles of the optimum design for opo are discussed . the experimental investigations of noncritical phase matching
以耦合波方程為基礎(chǔ),分析和計(jì)算了光學(xué)參量振蕩器的轉(zhuǎn)換效率、抽運(yùn)閾值、譜線寬度等特性,并在此基礎(chǔ)上討論了如何選擇opo的各項(xiàng)參數(shù)。 - Then we focus on support vector machine and discuss its theory foundation , basic concepts , and crucial techniques of support vector machine . with these background , we further study several generally algorithms about support vector machine , especially for plait ' s smo ( sequential minimal optimization ) algorithm . points out an important source of inefficiency in platt ' s sequential minimal optimization ( smo ) algorithm that is caused by the use of a single value , then present an improved smo algorithm employed two threshold parameters
然后在研究了支持向量機(jī)的理論基礎(chǔ)及基本概念和要解決的關(guān)鍵技術(shù)問題之后，又對(duì)當(dāng)前各種比較通用的支持向量機(jī)訓(xùn)練算法進(jìn)行了研究，比較了各種算法的優(yōu)劣，尤其深入研究了platt等人的smo ( sequentialminimaloptimization )算法，指出這種smo算法低效的主要原因是采用了單一的閾值參數(shù)，然后參考keerthi等人的思想，提出了一種使用兩個(gè)閾值參數(shù)的改進(jìn)的smo算法，在uci數(shù)據(jù)集和我們的iga腎病數(shù)據(jù)集上的試驗(yàn)結(jié)果表明，這種改進(jìn)的smo算法在訓(xùn)練速度上有一定的提高。 - It's difficult to find threshold parameter in a sentence. 用threshold parameter造句挺難的
