Feature Engineering Guide

Create effective features that improve machine learning model performance.

Usage

Describe your dataset and target to get feature engineering recommendations.

Examples

  • "Engineer features for a customer churn prediction model"
  • "Create time-based features from transaction timestamps"
  • "Generate interaction features for a recommendation system"

Guidelines

  • Understand the domain before creating features
  • Start with simple features before complex ones
  • Handle missing values before feature creation
  • Use cross-validation to validate feature importance
  • Document the rationale for each engineered feature
