autoclusternode properties

The Auto Cluster node estimates and compares clustering models, which identify groups of records that have similar characteristics. The node works in the same manner as other automated modeling nodes, allowing you to experiment with multiple combinations of options in a single modeling pass. Models can be compared using basic measures with which to attempt to filter and rank the usefulness of the cluster models, and provide a measure based on the importance of particular fields.

Example

node = stream.create("autocluster", "My node")
node.setPropertyValue("ranking_measure", "Silhouette")
node.setPropertyValue("ranking_dataset", "Training")
node.setPropertyValue("enable_silhouette_limit", True)
node.setPropertyValue("silhouette_limit", 5)

Table 1. autoclusternode properties
`autoclusternode` Properties	Values	Property description
`evaluation`	field	Note: Auto Cluster node only. Identifies the field for which an importance value will be calculated. Alternatively, can be used to identify how well the cluster differentiates the value of this field and, therefore; how well the model will predict this field.
`ranking_measure`	`Silhouette` `Num_clusters` `Size_smallest_cluster` `Size_largest_cluster` `Smallest_to_largest` `Importance`
`ranking_dataset`	`Training` `Test`
`summary_limit`	integer	Number of models to list in the report. Specify an integer between 1 and 100.
`enable_silhouette_limit`	flag
`silhouette_limit`	integer	Integer between 0 and 100.
`enable_number_less_limit`	flag
`number_less_limit`	number	Real number between 0.0 and 1.0.
`enable_number_greater_limit`	flag
`number_greater_limit`	number	Integer greater than 0.
`enable_smallest_cluster_limit`	flag
`smallest_cluster_units`	`Percentage` `Counts`
`smallest_cluster_limit_percentage`	number
`smallest_cluster_limit_count`	integer	Integer greater than 0.
`enable_largest_cluster_limit`	flag
`largest_cluster_units`	`Percentage` `Counts`
`largest_cluster_limit_percentage`	number
`largest_cluster_limit_count`	integer
