In Machine Learning, predicting the future is very important. How Does it Work? Python has methods for finding a relationship between data-points and to draw a line of linear regression. We will show you how to
所以这次就决定使用经典教材《Machine Learning in action》。因为开学得换work station ,怕到时候代码又丢了,所以就索性开个博客,把代码上传上来。 因为书上的原代码有很多错误,并且网上的许多博客的代码也是没有改正的,这次我把修正过的代码po上来 version:python3.5 talk is cheap show me the code 函数定义代码 ...

在数学建模中,我们经常会遇到这样的问题:根据xx症状判断是否得病、根据xxx指标判断是否违约。对于这种只包含“是和否”两类的答案的二分类问题,逻辑回归最为适用。 1.逻辑回归是什么 逻辑回归是机器学习基本算法之一,可以看作特殊的一般回归。 通过线性回归,一般可以得到这样的表达式: ...
