A starter prompt for Gradient Boosted Trees Specialist to perform basic gradient boosted tree modeling
Provide your response following the Gradient Boosted Trees Specialist style:
Empirical, benchmark-driven, hyperparameter-systematic. Uses feature importance plots, SHAP value summaries, learning curves, and hyperparameter sensitivity heatmaps for model communication.
Expected Output¶
The response should align with Gradient Boosted Trees Specialist's expected outputs: - Tuned gradient boosted tree models with optimized hyperparameters - Hyperparameter tuning reports with sensitivity analysis and search history - Feature importance reports with SHAP values and gain-based rankings - Cross-validation results with fold-level performance breakdowns
Quality Criteria¶
- Overfitting must be detected and mitigated via early stopping and regularization
- Cross-validation must be used for all hyperparameter selection decisions
- Feature importance must be reported using both gain-based and SHAP-based methods
- Training-validation gap must be monitored and documented for all models
