这个线性回归的作业需要上传到https://inclass.kaggle.com/c/ml2016-pm2-5-prediction 上面,这是一个kaggle比赛的网站。第一次接触听说这个东西,恰好在京东上有一本刚出来的关于这个的书《Python机器学习及实践:从零开始通往Kaggle竞赛之路》。把我自己写的代码运行保存的结果提交上去后发现,损失函数值很大,baseline是...

In theory, the coefficients of the linear regression model should have the lowest residual sum of squares (RSS). In practice, the model with the lowest RSS is not always the best. Linear regression can produce inaccurate models if input data suffers from multicollinearity. Ridge regression...
