Description
Farmer John's cows have discovered that the clover growing along the ridge of the hill (which we can think of as a one-dimensional number line) in his field is particularly good.

L2范数 除了L1范数,还有一种更受宠幸的规则化范数是L2范数: ||W||2。它也不逊于L1范数,它有两个美称,在回归里面,有人把有它的回归叫“岭回归”(Ridge Regression),有人也叫它“权值衰减weight decay”。这用的很多吧,因为它的强大功效是改善机器学习里面一个非常.....

机器学习就是把无序的数据转换成有用的信息。
机器学习的主要任务就是分类,通过通过训练数据训练算法,最终可以将实际的数据分到合适的类别中
监督学习算法:预测目标变量的值
k-means算法,线性回归
朴素贝叶斯算法,局部加权线性回归
支持向量机,ridge回归
决策树,lasso最小回归系数估计
无监督学习算法:不需要预测目标变量的值
k-均值,最大期望算法
DBS...
