在分类和回归问题中,我们通过构建一个关于x的模型来预测y。这种问题可以利用广义线性模型(Generalized linear models,GMLs)来解决。构建广义线性模型我们基于三个假设,也可以理解为我们基于三个设计决策,这三个决策帮助我们构建广义线性模型: ,假设 满足一个以为参数的指数分布。例如,给定了输入x和参数θ,那么可以构建...
Generalized linear models are defined by three components: (1) a linear regression equation, (2) a specific error distribution, and (3) a link function which is the transformation that links the predicted values for the dependent variable to the observed values. ...
本段主要分析了将Lasso L1惩罚进行稀疏筛选的思想应用到更一般的线性模型中——广义线性模型,如常见的Logistic、Poission、Cox等,另外也分析了SVM+L1惩罚的表现及其和Logistic的异同。如有兴趣,可以看我当时的讲解视频。
