binning
What It Means
Binning is the practice of grouping continuous data values into broader categories or ranges instead of treating each individual value separately. For example, instead of tracking exact customer ages like 23, 24, 25, you create age groups like '20-29' or '30-39'. This simplifies data analysis by reducing noise and making patterns easier to identify.
Why Chief AI Officers Care
Binning directly impacts AI model performance and business insights by determining how granular your analysis can be. Poor binning choices can mask important business patterns or create false correlations that lead to bad decisions. It also affects regulatory compliance, as some industries require specific data groupings for reporting, and overly broad bins might hide discriminatory patterns in AI models.
Real-World Example
A retail company bins customer purchase amounts into categories like 'low spenders ($0-50)', 'medium spenders ($51-200)', and 'high spenders ($201+)' instead of tracking exact dollar amounts. This helps their recommendation AI focus on broader spending behaviors rather than getting confused by the difference between someone who spends $67 versus $68, leading to more effective customer segmentation and targeted marketing campaigns.
Common Confusion
People often think binning is just about making data simpler, but the key confusion is that binning choices permanently alter what insights you can extract from your data. Once you bin ages into decades, you can never recover patterns that might exist at the individual year level.
