[Machine Learning] Andrew Ng on Coursera (Week 1)

Week 1 的内容主要有: 机器学习的定义监督式学习和无监督式学习线性回归和成本函数梯度下降算法线性代数回归主要是了解一下机器学习的基本概念,重点是学习线性回归模型,以及对应的成本函数和梯度下降算法. 以上两幅图基本上就是week 1 的重点了. 下文是我做的比较粗糙的一个关于week 1 的总结.其中线性代数部分就省略掉了,大学里基本都有学过矩阵相关的操作.…

Machine Learning(Andrew Ng)学习笔记

1.监督学习(supervised learning)&非监督学习(unsupervised learning) 监督学习:处理具有若干属性且返回值不同的对象.分为回归型和分类型:回归型的返回值是连续的,分类型的返回值是离散的. 非监督学习:将具有若干属性的相同对象分为不同的群体. 2.线性回归模型(监督学习) 2.1 一些符号 m——训练样本数目 x——输入变量 y——输出变量 (x,y)——一个训练样本 (x(i),y(i))——第i个训练样本 h——假设(hypothesis)——预测函数…
