机器学习中遗忘的数学知识 最大似然估计( Maximum likelihood ) 最大似然估计,也称为最大概似估计,是一种统计方法,它用来求一个样本集的相关概率密度函数的参数.这个方法最早是遗传学家以及统计学家罗纳德·费雪爵士在1912年至1922年间开始使用的. 最大似然估计的原理 给定一个概率分布,假定其概率密度函数(连续分布)或概率质量函数(离散分布)为,以及一个分布参数,我们可以从这个分布中抽出一个具有个值的采样,通过利用,我们就能计算出其概率: 但是,我们可能不知道的值,尽管我们知道…

1. scikit-learn介绍 scikit-learn是Python的一个开源机器学习模块,它建立在NumPy,SciPy和matplotlib模块之上.值得一提的是,scikit-learn最先是由David Cournapeau在2007年发起的一个Google Summer of Code项目,从那时起这个项目就已经拥有很多的贡献者了,而且该项目目前为止也是由一个志愿者团队在维护着. scikit-learn最大的特点就是,为用户提供各种机器学习算法接口,可以让用户简单.高效地进行数…
