What is correlation between trees in Random Forest?
Updated May 17, 2026
Short answer
Low correlation between trees improves Random Forest performance.
Deep explanation
Random sampling of data and features ensures trees learn different patterns, reducing correlated errors.
Real-world example
Used in anomaly detection systems.
Common mistakes
- Assuming identical trees improve performance.
