**TLDR:** A measurable attribute or input variable that describes a data instance from the model’s perspective.

<p>A feature is a core element that determines through which window the model sees the world. A customer’s age, a temperature measurement from a sensor, or a recurring pattern in a text may all be treated as features. How well a model can learn depends heavily on the quality of the features it receives. For that reason, a feature should not be seen as just a data column, but as the raw material of model intelligence. Strong features make strong models possible, while weak features can limit even the best algorithms.</p>
