Model Node

A model node allows you to add models to a workflow that were not built in the workflow. For example, you can specify a model that was built using either of the ODM APIs.

The models in a Model node must satisfy the Model Constraints.

The Model node takes no input. A Model node can be an input to any node that accepts models (such as the Apply and Test nodes, at least for some of the function types). For example, if a model node contains Classification or Regression models, it can be input to a test node. Test data must be prepared in the same way that the build data was prepared.

The following topics describe model nodes:

Model nodes rely on database resources for their definition. It may be necessary to refresh a node definition if the database resources change (for example, if the resources are deleted or recreated). See Refresh Data Node, Model Node, or Update Table Node for details.
