If most of the values in a column are the same value, then that column may not provide useful information for model building.
By default, the Filter Columns node examines each column in a sample of the data to see if
NULL
values exceeds 95%.You can change these values, for example, you can check to see if the number of constant values exceeds 85%.
After node runs, hints tell you if any column fails these requirements.
You must decide which columns to ignore in subsequent nodes (that is, which columns are not passed on). To ignore a column,
click in the
Output column.
