What is Underfitting?
When an AI model is too simple to capture the patterns in the data and performs poorly on everything.
Why It Matters
Underfitting means your model has not learned enough and needs more complexity or better training data.
Real-World Example
Trying to predict house prices using only the number of bedrooms when location and size also matter.
“Understanding terms like Underfitting matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
