About Classifier Nodes in Cognitive Analytics

The Properties window for a Classifier node contains the items that are described in the following table.

Item	Description	Notes
	Specifies the Fuzzy Logic or Machine Learning script that will run when the cognition is executed.	Select to browse to the Fuzzy Logic or Machine Learning script that you want to add to the Script node. Scripts developed by Meridium, Inc. are available in the \\Public\Meridium\Modules\Cognitive Analytics\Scripts\ Catalog folder.
Standard List Reference Field	Specifies values that identify sub-sets of the script’s Standard List (e.g., Equipment Class values).	This field is optional and enabled only when a Fuzzy Logic script has been specified. When the cognition is executed, values in the specified field are compared to List Reference values in Classifier Standard List records to determine which sub-set(s) of the script’s Standard List to use.

Consider the following nodes and connections.

The maintainableItem.py Classifier node receives values from the Taxonomy Class Description, the Event Long Description, the Event Short Description, and the Maintainable Item Description input fields, and then uses the maintainableItem.py script to classify the values.

The Maintainable Item output field receives the predicted value produced by the maintainableItem.py script.

The following image shows what the Properties window looks like for the maintainableItem.py Classifier node.

In this example, the Taxonomy Class Description input field is selected in the Reference box and is used to pass List Reference values to the maintainableItem.py script. The values from the Taxonomy Class Description input field will limit the predictions produced by the script to the sub-sets of Standard Values that correspond to the List References in the Maintainable Item Standard List.
