Build (Classification)

The Build node enables you to specify or change the characteristics of the models to build. To edit the characteristics of the models to build, follow these steps:

1. In the Target field, select the target from the drop-down list. The list consist of attributes from the table or view specified in the Data Source node that is connected to the build node.

   You must specify a target. All models in the node have the same target.

2. In the Case ID field, select one attribute from the drop-down list. This attribute must uniquely identify a case.
   If you specify a case ID, all models in the node will have the same case ID.

   
   

   Note: If you do not specify a case ID, then the processing will be slower because a table must be generated. The case ID is required to generate GLM diagnostics. A case ID is required if a column in the input data is a nested column. That is, very dense and deep (lots of name-value pairs). If there is no case ID, then the sorting operations may fail.

   
   

3. In the Models Settings section, select which models you want to build. For a Classification node with a binary target, Naive Bayes (NB), Decision Tree (DT), Support Vector Machine (SVM), and Generalized Linear Models (GLM) models are specified by default.

   • To delete a model, select the model and click .

   • To edit a model, select the model and click .

   • To add models, click .

   • To copy an existing model, select the model to be copied and click .

By default, the model is tested using a test data set created by splitting the build data set. If you do not want to test the model in this way, go to the Classification Node Test section in Classification node Properties pane. You can instead use a Test Node and a test data source to test the model.
