New method improves random forest classification accuracy

Researchers have developed a new method to improve the reliability of random forest classification models by analyzing the decision paths within individual trees. This approach reweights trees based on the patterns of class label flips along their root-to-leaf paths, addressing the limitation of treating all trees equally. The proposed class-conditional ratio weighting scheme demonstrated statistically significant accuracy improvements over standard random forests on 30 binary classification benchmarks, while avoiding common regressions in recall.
