Are you consistently losing points on Decision Trees because of letting the tree grow without a max depth limit? If so, you're making the exact same error as 80% of your class.
Your Timeline
- Minute 1: Identify the variables. Don't start solving.
- Minute 2: Check for edge cases. Are you about to commit the sin of letting the tree grow without a max depth limit?
- Minute 3-5: Execute. Keep this application in mind: An unconstrained decision tree will create a separate leaf node for almost every single training example, leading to massive overfitting. Always prune or set a max depth.
Stick to the timeline. Methodical execution beats panicked guessing every single time.
