Capstone: churn prediction · Predict which customers will leave, and measure it properly. About 45 minutes.
Other terms from the same lesson
- holdout group: Customers or data deliberately left out, so you can compare against them and see the real effect.
- lift: How many times better a targeted group does than average: if 40% of the top 5 churn against 20% overall, the lift is 2.
- permutation importance: How much a model's score drops when one column is shuffled. A big drop means the model leans on that column.
