Collecting predictions and creating custom metrics
Using the last_fit()
modeling workflow also saves time in collecting model predictions. Instead of manually creating a tibble of model results, there are helper functions that extract this information automatically.
In this exercise, you will use your trained model, telecom_last_fit
, to create a tibble of model results on the test dataset as well as calculate custom performance metrics.
Your trained model, telecom_last_fit
, has been loaded into this session.
