Regression

A supervised learning task that predicts a continuous numeric value.

Definition

Regression models estimate a real-valued target from input features. Linear regression, decision tree regressors and neural networks can all perform regression. Typical metrics are mean absolute error, root mean squared error and R-squared.

Example

Forecasting next quarter's revenue in dollars.

Exam tip

A numeric output that can take any value in a range means regression; logistic regression is actually a classifier.
