最小二乘线性回归(第3篇文章)用于定量响应,而逻辑回归(第4篇文章)通常用于定性(两类或二进制binary)响应,因此它通常用作分类方法。但是由于二进制可以估计类概率,因此也可以将其视为回归方法。在定量或定性响应的情况下,可以使用一些统计方法,例如K近邻(第2篇文章和第4篇文章)和增强方法(第8篇文章)。 我们倾向...
带你读机器学习经典(一): An Introduction to Statistical Learning (Chapter 1&2) 0. 前言 - 我为什么要写这一系列文章? 自从上个月回答了【如何看待「机器学习不需要数学,很多算法封装好了,调个包就行」这种说法?】以后,我收到了很多朋友的评论和私信,希望我能谈谈新手如何快速入门机器学习。 为了给大家一个...

使用最小二乘法进行线性回归时，需假设样本数据是随机独立抽取自总体。这方法不仅适用于一元线性回归，也适用于多元线性回归。通过最小二乘法，我们能获得闭式解，使模型具有较高的预测准确性。距离度量在回归分析中至关重要，它通过衡量预测值与实际值之间的相似度，评估模型的预测准确性。最小二乘法正...
