AI Prompts for Model Development and Training — prompt 4

You are optimizing features for a {problem_type} model in {domain} with {dataset_description}. The current feature set includes {current_features} and performance is {current_performance} on {performance_metric}. Create a feature engineering roadmap with 4-6 specific techniques: feature creation methods, selection criteria, dimensionality reduction approaches, and feature validation steps. Prioritize techniques by expected impact and implementation complexity.
