Gradient Boosted Trees Specialist — Debug Workflow

Description: Fix issues and errors in artifacts

When to Use

Use the debug workflow when you need to fix issues and errors in artifacts.

Input Requirements

• Structured datasets with feature type annotations (numeric, categorical, ordinal)
• Hyperparameter search space definitions and computational budgets
• Evaluation metrics and business performance targets
• Cross-validation strategy specifications and data splitting requirements

Process

1. Initialize — Set up the debug context for Gradient Boosted Trees Specialist
2. Execute — Perform the debug operation following Gradient Boosted Trees Specialist's style
3. Validate — Check output against quality gates
4. Handoff — Deliver results to downstream personas

Output

• 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 Gates

• 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
