  • Calculate the MAE by comparing the actual with the predicted values for the validate data and assign it to the validate_mae column.
  • Print the validate_mae column (note how they vary).
  • Calculate the mean of this column.

Note: The actual values of the validate fold (validate_actual) has already been added to your cv_data dataframe.
