【Tensorflow】逻辑斯特回归(Logistic Regression)的简单实现 Introduction 为了简单的介绍和讲解一下Tensorflow的基本操作, 我决定做一个简单的逻辑斯特回归实现与代码讲解, 但不太会用Markdown的方式来展现一个JupyterNotebook, 姑且就按照“说明—实例”的方式来解释逐个代码块好了。 Import packages Loading training dat...

Pytorch实现Logistic回归二分类 摘要:本文主要介绍使用深度学习框架Pytorch实现简单的Logistic回归模型,进而实现简单的分类问题。 一.逻辑回归简述 逻辑回归实质上是线性回归,把特征线性求和(一阶)之后再使用Sigmoid函数将结果映射到[0,1]区间,得到分类结果为1的概率大小。具体表达式如下: h(w,x) =1/(1+exp(-(w*x...
