Prediction (Supervised ML)

Prediction (aka supervised machine learning) is used when you have a target variable that you want to predict. For instance, you may want to predict the price of apartments in New York City using the size of the apartments, their location and amenities in the building. In this case, the price of the apartments is the target, while the size of the apartments, their location and the amenities are the features used for prediction.

Note

Our Machine Learning Basics tutorial provides a step-by-step explanation of how to create your first prediction model and deploy it for scoring of new records.

The rest of this document assumes that you have followed this tutorial.
