Multi-Dataset Comparison Study

⚠️ Note: Results in this notebook may vary significantly depending on hyperparameters, dataset characteristics, and random initialization. Some stable-cart configurations may not always yield improved results compared to baselines.

This notebook demonstrates the core methodology of stable-cart: creating individual decision trees with modified tree-building processes.

Why stability matters: Standard decision trees are notoriously unstable - small changes in training data can lead to completely different trees and predictions. Stable-CART methods modify the tree-building process to create trees that are more consistent across different training runs.

Breast Cancer Dataset: Stability vs Accuracy Analysis

Let’s demonstrate the stability-accuracy trade-off using the breast cancer dataset. After fixing a critical bug in the stable-cart package (split candidate generation), we can now show working comparisons between standard and stable tree methods.

Bug Fixed: The original implementation had max_candidates // n_features which gave 0 splits per feature for high-dimensional datasets, preventing any tree construction. This has been patched.

✅ Working models: 4/4

📊 PERFORMANCE vs SKLEARN BASELINE:

CART baseline: AUC = 0.910
  RobustPrefixHonest: AUC = 0.746 (82.0% of CART)
  LessGreedyHybrid: AUC = 0.922 (101.4% of CART)

RandomForest baseline: AUC = 0.990
  RobustPrefixHonest: AUC = 0.746 (75.3% of RandomForest)
  LessGreedyHybrid: AUC = 0.922 (93.1% of RandomForest)

🔧 NOTE: Parameters optimized through aggressive grid search.
   Key findings: Deep trees (max_depth=15) and minimal validation sets essential
   Data allocation: ~94% for tree building, ~6% for validation/estimation
   Stable-cart models now achieve 70-80% of sklearn baseline performance!
