当采用L1正则化时,则变成了LassoRegresion;当采用L2正则化时,则变成了Ridge Regression;线性回归未采用正则化手段。通常来说,在训练模型时是建议采用正则化手段的,特别是在训练数据的量特别少的时候,若不采用正则化手段,过拟合现象会非常严重。L2正则化相比L1而言会更容易收敛(迭代次数少),但L1可以解决训练数据量...
Welcome To My Blog Linear Regression 线性回归(Linear Regression)是一种线性模型(linear model),它将各个特征进行线性组合,实现对新输入的预测 线性回归可解释性很强,因为特征对应的权值大小直接衡量了这个特征的重要性 表示形式 设每个输入x_i都有m个特征,每个特征x_ij对应一个权值w_j 对于一个输入 现有训练集...

The task of regression is to predict label values based on feature values.We often create a label by projecting the values of a feature in the future.For instance, if we would like to predict the price of a stock for next month using historical monthly data, we would create the label ...
