Data table derivation operations

Create new data tables by manipulating an existing data table.

Overview

Use these methods to preprocess your data programmatically in Create ML before training a model. For example, you can create a data table by merging two data tables, fill in missing values, and then discarding duplicate rows.

All of these methods create new data tables, leaving the original data table unmodified.
