请问正确选项在讲义第几页何处？

问题如下：

Based on Achler’s grid search analysis, the current model can be characterized as:

选项：

underfitted

having low variance

exhibiting slight regularization

解释：

C is correct. Slight regularization occurs when the prediction error on the training dataset is small, while the prediction error on the cross- validation data set is significantly larger. This difference in error is variance. High variance error, which typically is due to too many features and model complexity, results in model overfitting.

A is incorrect. The current model has high variance which results in model overfitting, not underfitting.

B is incorrect. The difference between the prediction error on the training dataset and the prediction error on the cross-validation dataset is high, which means that the current model has high variance, not low.
