The following node is available in the Open Source KNIME predictive analytics and data mining platform version 2.7.1. Discover over 1000 other nodes, as well as enterprise functionality at http://knime.com.
This node takes two input tables: the first table contains all objects/rows from which subsets are selected. The second input table contains a collection of rows keys in each row, which represent the selected rows/objects after a subset selection. For each subset the objective functions entered in the dialog are computed and appended to the second input table.
0 | Datatable with all rows to choose from during evaluating subsets |
1 | Datatable with a collection column that contains the selected row keys |
0 | The objective values for each subset from the second input table. |
