Choose a Tree, Random Forest, or Boosting Model

Choose a tree model from operational trade-offs, not score alone.

#trees#random forest#boosting#model selection

Scenario

Churn candidates: shallow tree CV 0.76, variation 0.05, high interpretability; Random Forest 0.82, 0.02, medium interpretability; Gradient Boosting 0.85, 0.03, lower interpretability and more tuning.

Problem statement

Recommend the appropriate model for different priorities.

Your Task

  1. Choose when interpretability matters most.
  2. Choose a stable modest-tuning baseline.
  3. Choose when validated performance justifies complexity.
  4. Explain why importance is not causality.
