因为光看模型在训练集上的表现容易导致过拟合,因此回归模型通常有两种评价方式,一种是看验证/交叉验证的结果,另一种是对训练集上的表现结果进行修正,常见指标有:AIC,BIC,Cp,adjusted R2。 用验证/交叉验证方式评价回归模型性能的指标(Performance Evaluation Metric)通常有: 1.平均绝对误差(Mean Absolute Error, MAE...
Check Performance in Models Pane After training a model in Regression Learner, check the Models pane to see which model has the best overall score. The best RMSE (Validation) is highlighted in a box. This score is the root mean squared error (RMSE) on the validation set. The score ...
