Edit Nominal Domain

Resorts and/or inserts interactively possible values to the domain of a certain column of the input table. This allows the configuration of downstream nodes on an amended domain list, e.g. a histogram that should show an empty bin for a value that is not actually present in the data. Also, the sorting on the domain values can be changed. This might be useful for instance for many predictor nodes, which add a new column for each possible value to the prediction output table, whereby the order of the columns is determined by the ordering in the domain.

Options

Configured columns
The list of columns for which the domain values should be edited.
  • Column: Selects the column for which the domain values should be edited. Non-string typed columns are filtered out.
  • Added domain values: Specify values to be added to the domain. The values appear as part of the sorted domain values and are marked as new (e.g. 'value (new)'). Values that are already part of the domain are ignored.
  • Sorted domain values: Specify the order of the domain values (including newly added values). The position of values that are not yet part of the domain (unknown values) is determined by the special entry Any unknown value.
If a modified column is not present in data
Determine the behavior if a modified column is invalid since it no longer exists in the input table.
  • Fail: The node execution fails.
  • Ignore column: The invalid columns are kept unchanged.
If a modified column has an incompatible type
Determine the behavior if a modified column is invalid since it is no longer of type "String".
  • Fail: The node execution fails.
  • Ignore column: The invalid columns are kept unchanged.
