Removing correlated predictors with recipes
Removing correlated predictor variables from your training and test datasets is an important feature engineering step to ensure your model fitting runs as smoothly as possible.
Now that you have discovered that monthly_charges
and avg_data_gb
are highly correlated, you must add a correlation filter with step_corr()
to your feature engineering pipeline for the telecommunications data.
In this exercise, you will create a recipe
object that removes correlated predictors from the telecommunications data.
The telecom_training
and telecom_test
datasets have been loaded into your session.
