Description\Parameters |
Partition Column Name |
Name of the new column to be created. Data is partitioned always into two groups. We call those groups the role. |
Partition Mode |
Partition By Fraction splits data into training/scoring records by fraction, i.e. 80% of records become training, and 20% become scoring. Partition By Record Count assigns an exact number of records to training/scoring, i.e., assign the first 10 records to training, or the last 5 records to scoring. |
Percent Training |
Percent of the data set that will have the Training Value assigned to it. |
Percent Scoring |
Percent of the data set that will have the Scoring Value assigned to it. |
Training Value |
Text value to be assigned to the Percent Training fraction. |
Scoring Value |
Text value to be assigned to the Percent Scoring fraction. |
Row Assignment |
Select Training Records to set the exact number of training records; the rest will become scoring records. Select Scoring Records to set the exact number of scoring records; the rest will become training records. |
Partition Records |
Number of records to assign to the selected Row Assignment setting. |
Sample Randomly |
Sample Randomly assigns training/scoring rows at random throughout the data set. Split Time Series Data splits rows into training/scoring while maintaining order. |
Random Seed |
If Static, use the same seed value each time this node is run. If Random, use a new seed value each time. |
Seed Value |
Number used to seed the random split between the scoring and training fraction. Changing this number will change the random distribution. |
Split Columns |
The selected column(s) will be used to split the data set over. Each new subset will be assigned to training/scoring. |
Sort By Columns |
Sort data rows by these columns. |
