The RFM Framework
Explore how to transform raw transaction logs into key RFM features—recency, frequency, and monetary value—that summarize customer behavior. Understand how these features support segmentation, churn prediction, and lifetime value modeling. Learn practical techniques for feature engineering using pandas to prepare data for machine learning pipelines.
Customer analytics teams often need to transform raw transaction logs into structured features that drive business decisions and machine learning models. The RFM framework (recency, frequency, and monetary value) offers a proven approach for summarizing customer behavior in a way that aligns with both business objectives and technical requirements. By aggregating transactional data into interpretable metrics, RFM enables practitioners to bridge the gap between data engineering and downstream modeling tasks. In this lesson, you will learn how to engineer RFM features using pandas, interpret their business significance, and prepare these features for use in machine learning pipelines.
Introduction to the RFM framework and its role in ML
The RFM framework is a foundational tool in business analytics and applied machine learning for customer data. It condenses complex purchase histories into three key metrics:
Recency: How recently a customer made a purchase.
Frequency: How often a customer makes purchases.
Monetary value: How much a customer spends.
These dimensions capture the core of customer engagement and value, making them essential for segmentation, targeting, and predictive modeling. In practice, RFM features are engineered from raw transaction data using libraries like pandas, enabling scalable and reproducible workflows.
Note: RFM is not limited to marketing. Its features are widely used in churn prediction,...
