error propagation

What It Means

Error propagation describes how small mistakes or uncertainties in your data inputs get magnified and spread through your AI systems, potentially creating much larger problems in your final results. When your AI model makes decisions based on flawed or uncertain data, those flaws don't stay contained - they cascade through the entire system and can significantly distort your outputs.

Why Chief AI Officers Care

A single bad data source or measurement error can completely undermine the reliability of your AI predictions, leading to poor business decisions, regulatory compliance failures, or customer trust issues. Understanding error propagation helps you identify which data inputs are most critical to get right and where to invest in data quality improvements for maximum impact.

Real-World Example

A retail AI system predicting demand uses sales data, weather forecasts, and supplier lead times - if the weather data is consistently off by 10%, this error amplifies through the demand calculations and could result in 30% inventory overstock during predicted 'rainy seasons' that never materialize, costing millions in excess inventory.

Common Confusion

People often think error propagation only affects the final output quality, but it actually determines which parts of your data pipeline are most vulnerable and where small improvements in accuracy will have the biggest business impact.
