一、说明 IG是information gain 的缩写,中文名称是信息增益,是选择特征的一个很有效的方法(特别是在使用svm分类时)。这里不做详细介绍,有兴趣的可以googling一下。 chi-square 是一个常用特征筛选方法,在种子词扩展那篇文章中,有详细说明,这里不再赘述。 二、weka中的使用方法 1、特征筛选代码...
It can be seen from the above analysis that in the standard CKF algorithm, the Cholesky transformation is required to factorize the square root of the error covariance matrix P before calculating cubature points, that is: 𝑃=𝑆𝑆𝑇P=SST (39) where S is a lower triangular matrix. 3....
