Microsoft Machine Learning Studio: Understanding 'Select Columns in Dataset' Module Properties

The sequence of entering the column names in the 'Select Columns in Dataset' module's 'Properties' is not important. This is because the module selects the columns based on their names and not their positions in the dataset.

The purpose of checking the option 'Allow duplicates and preserve column order in selection' is to allow the module to select columns with duplicate names and maintain their original order in the selection. This option is useful when the dataset has columns with the same name, and the user wants to select all of them. By default, the module removes duplicate columns and selects only one column with the same name. However, checking this option ensures that all columns with the same name are selected and their original order is preserved.
