Feature
An individual measurable property or characteristic of data used as input to a machine learning model.
In-depth explanation
Features are the variables that the model uses to make predictions. Good features capture relevant information and discriminate between different outputs. Feature engineering-creating new features from raw data-is often crucial for model performance. Features can be numerical, categorical, text, images, or other data types.
