KNIME Base Nodes version 3.7.1.v201901291053 by KNIME AG, Zurich, Switzerland

The input table is split into two partitions (i.e. row-wise), e.g. train and test data. The two partitions are available at the two output ports. The following options are available in the dialog:


Specify the absolute number of rows in the first partition. If there are less rows than specified here, all rows are entered into the first table, while the second table contains no rows.
The percentage of the number of rows in the input table that are in the first partition. It must be between 0 and 100, inclusively.
Take from top
This mode puts the top-most rows into the first output table and the remainder in the second table.
Linear sampling
This mode always includes the first and the last row and selects the remaining rows linearly over the whole table (e.g. every third row). This is useful to downsample a sorted column while maintaining minimum and maximum value.
Draw randomly
Random sampling of all rows, you may optionally specify a fixed seed (see below).
Stratified sampling
Check this button if you want stratified sampling, i.e. the distribution of values in the selected column is (approximately) retained in the output tables. You may optionally specify a fixed seed (see below).
Use random seed
If either random or stratified sampling is selected, you may enter a fixed seed here in order to get reproducible results upon re-execution. If you do not specify a seed, a new random seed is taken for each execution.
