C2_W3_Lab01 Question

Clearly, we can see that the model with the lowest CV MSE was model 1 but model 3 was selected as the best model. Why was the model with the least CV MSE not selected? Please correct me if I’ve misunderstood the concept here.

Did you not read the text provided above the cell?

Hi @Dipen_Pandit,

These are my results and can explain the choice of Model 3:

Maybe you had run the cells in different orders, or modified some cells? The easiest way to get the default results is to get a fresh copy of the notebook, and run all the cells in order. Here are some steps that you can follow to get a new copy of the notebook.

Cheers,
Raymond
