Logistic Regression是一种广泛使用的分类算法，它的主要思想是将输入变量的线性组合映射到0到1之间的概率，用于预测二元输出变量的概率。逻辑回归模型，是一种广义的线性回归分析模型。日常工作生活中我们会遇到很多的1,0分类问题，比如考试通过还是不通过、是否患某种疾病等等这样的问题都可以使用逻辑回归来解决。尽管它被称为“

Multinomial logistic regression The principle of multinomial logistic regression is to explain or predict a variable that can take J alternative values (the J categories of the variable), as a function of explanatory variables. The binomial case seen previously is therefore a ...

逻辑回归(Logistic Regression):既可以看做是回归算法,也可以看做是分类算法。通常作为分类算法,一般用于解决二分类问题。 线性回归模型如下: 逻辑回归思想是基于线性回归(Logistic Regression是广义的线性回归模型),公式如下: 其中, 称为Sigmoid函数 ...
