Now, we can deal with it as a ‘linear regression’ problem. Therefore, this polynomial regression is considered to be a special case of traditional multiple linear regression. So, you can use the same mechanism as linear regression to solve such problems. 所以,我们就用之前就用过的 **Linear...
Polynomial RegressionIf your data points clearly will not fit a linear regression (a straight line through all data points), it might be ideal for polynomial regression.Polynomial regression, like linear regression, uses the relationship between the variables x and y to find the best way to draw...
二、Polynomial Regression 但有的时候,y本身是由x取平方所得,无法找出来一条合适的线性回归线来拟合数据,该怎么办呢? 我们可以尝试将x取平方,取3次方等方法,多加尝试 三、误差分析 四、防止过拟合 用惩罚系数(penalty),即正则项(regularize the model) ...
