underfitting
What It Means
Underfitting happens when your AI model is too simple to learn the important patterns in your data. It's like trying to predict customer behavior with only one basic rule when you actually need several sophisticated rules to be accurate.
Why Chief AI Officers Care
Underfit models deliver poor business results because they miss crucial insights and make inaccurate predictions. This leads to failed AI initiatives, wasted investment, and lost competitive advantage when simpler models can't capture the complexity needed for real business decisions.
Real-World Example
A retail company builds a demand forecasting model that only considers last month's sales to predict inventory needs, ignoring seasonality, promotions, weather, and economic factors. The model consistently under-orders popular items during holidays and over-orders during slow periods, resulting in stockouts and excess inventory.
Common Confusion
People often think underfitting means the model needs more data, when it actually means the model architecture or features are too simple to capture the data's complexity. It's the opposite of overfitting, where models are too complex and memorize training data.
