A framework for robust optimization under uncertainty based on the use of the generalized inverse distribution function (GIDF), also called quantile function, is here proposed. Compared to more classical approaches that rely on the usage of statistical moments as deterministic attributes that define the...
1.By decreasing the higher limit of the object function step by step, applying method of the generalized inverse of matrices and Newton-Raphs.逐次收缩目标函数上限值,运用广义逆矩阵和牛顿—拉夫逊法求解,将OPF问题转化为一系列求解非线性不定方程组的一维优化逼近过程。 2.We introduce a generalized inver...
Cell array of the form{FL FD FI}that defines the link function (FL(mu)), the derivative of the link function (FD = dFL(mu)/dmu), and the inverse link function (FI = FL^(–1)). Each entry holds a function handle that accepts a vector of inputs and returns a vector of the sam...
This paper generalizes the conclusion of Perfect nonlinear S-boxes by Nyberg(1991), and introduces the conception of inverse regular generalized vector Bent function. It shows that for inverse regular generalized vector Bent functionf(m)(x) with even variables, m is no more than half of n. ...
You can choose one of the built-in link functions or define your own by specifying the link function FL, its derivative FD, and its inverse FI: The link function FL calculates f(µ). The derivative of the link function FD calculates df(µ)/dµ. The inverse function FI calculates ...
TF-IDF(Term Frequency-Inverse Document Frequency, 词频-逆文件频率) 是一种用于资讯检索与资讯探勘的常用加权技术。TF-IDF(计算相关度必备,否则不需要)是一种统计方法,用以评估一字词对于一个文件集或一个语料库中的其中一份文件的重要程度。字词的重要性随着它在文件中出现的次数成正比增加,但同时会随着它在语...
PG的全文检索排序考虑了文档不同部分的权重、词素的精确程度、出现频率维度(TF和IDF,Term Frequency-Inverse Document Frequency, 词频-逆文件频率)来计算相关性,不同的应用有不同的算法,甚至考虑文档的时效性,内置的排序函数仅提供了参考,作为自定义的样例。
这里g 就是传说中的 link function,h为 inverse link function 【Exponential Family and Generalized Linear Models】 [GLM 的基本思路] 由于GLM主要基于exponential family构建而成。此处,所有 response Y 都需要属于exponential family的分布。那么,到底什么样的分布属于exponential family呢? 首先,我们的故事将从简单而...
