quadratic loss function meaning in English

二次损失函数

The six sigma black belt will be able to use a quadratic loss function to compute the cost of a given process
译文：六西格玛黑带能够使用二次品质损失函数来计算给定过程的成本。
It is more suitable to the practice using qlf to measure quality . this paper discusses the defect of quadratic loss function and studies the models of inverted normal and inverted gamma loss function . we explore the relationship between qlf and signal - to - noise ( sn ) , put forward multivariate qlf model based on sn , which overcome the flaw that single - characteristic can not reflect multi - characteristic in practice
本文讨论了二次损失函数模型的局限，在此基础上研究了逆正态、逆伽玛损失函数模型；探讨了质量损失函数与信噪比的关系，提出了基于信噪比的多元质量损失函数模型，克服了单质量属性不能反映实际中多维质量属性的质量损失的弊端，实例证明该方法是可行的。
