What Is Bias in Data?

1 min

Data bias happens when the examples a model learns from don't fairly represent everyone or everything — so the model ends up being unfair too.

Imagine it like this: If you practiced free throws only on a hoop set too low, you'd get amazing at that hoop, but struggle on a regular one. Your training wasn't a fair representation of the real challenge — that's bias.

Preview — the rest of the lesson is for enrolled readers.
