partitionnode properties

Last updated: Jan 18, 2024

Partition node icon The Partition node generates a partition field, which splits the data into separate subsets for the training, testing, and validation stages of model building.

Example

node = stream.create("partition", "My node")
node.setPropertyValue("create_validation", True)
node.setPropertyValue("training_size", 33)
node.setPropertyValue("testing_size", 33)
node.setPropertyValue("validation_size", 33)
node.setPropertyValue("set_random_seed", True)
node.setPropertyValue("random_seed", 123)
node.setPropertyValue("value_mode", "System")

Table 1. partitionnode properties
`partitionnode` properties	Data type	Property description
`new_name`	string	Name of the partition field generated by the node.
`create_validation`	flag	Specifies whether a validation partition should be created.
`training_size`	integer	Percentage of records (0–100) to be allocated to the training partition.
`testing_size`	integer	Percentage of records (0–100) to be allocated to the testing partition.
`validation_size`	integer	Percentage of records (0–100) to be allocated to the validation partition. Ignored if a validation partition is not created.
`training_label`	string	Label for the training partition.
`testing_label`	string	Label for the testing partition.
`validation_label`	string	Label for the validation partition. Ignored if a validation partition is not created.
`value_mode`	`System` `SystemAndLabel` `Label`	Specifies the values used to represent each partition in the data. For example, the training sample can be represented by the system integer `1`, the label `Training`, or a combination of the two, `1_Training`.
`set_random_seed`	Boolean	Specifies whether a user-specified random seed should be used.
`random_seed`	integer	A user-specified random seed value. For this value to be used, `set_random_seed` must be set to `True`.
`enable_sql_generation`	Boolean	Specifies whether to use SQL pushback to assign records to partitions.
`unique_field`		Specifies the input field used to ensure that records are assigned to partitions in a random but repeatable way. For this value to be used, `enable_sql_generation` must be set to `True`.
