Feature
Definition
In machine learning, a feature is an individual measurable property or characteristic of a phenomenon being observed. Features are the inputs to your machine learning model.
Why It Matters
The quality of your features is critical to the performance of your model. Choosing informative, discriminating, and independent features is a key part of the art of machine learning.
Contextual Example
To predict a house's price, you might use features like its square footage, number of bedrooms, age, and location. Each of these is a feature.
Common Misunderstandings
- The process of creating and selecting features is called "feature engineering".
