调参的目的是通过寻找最优的超参数组合,使得模型在验证集或交叉验证中的性能最好,从而提高模型的泛化能力。 2. LinearRegression 中的调参 对于最基本的线性回归模型(如最小二乘法求解的普通线性回归),通常没有太多超参数需要调节,因为其有一个闭合解。但在实际应用中,我们常常采用一些带有正则化的线性回归模型,如R...
You can see that linear regression can be used in almost every aspect of the business. By using linear regression models, we can uncover patterns and relationships in the data that can be used to leverage monetary benefits for the business. With forecasting, a business can always predict the ...
