Classification Mining Activity

This mining activity builds and tests a classification model.

There are several algorithms that build classification models. The title of the activity indicates the algorithm used. For example, a Naive Bayes Mining Activity builds and tests a classification model using the Naive Bayes algorithm.

For information about classification models, see Classification Models. For general information about mining activities, see Mining Activities.

You can view the options for a step by clicking Options in the step. You can change options for a step that has not executed or was reset.

You must execute the steps of an activity in order. You can execute the steps of an activity in several ways:

To execute all checked steps of an activity in order, click Run Activity just above the list of steps.

To execute an individual step, click Run in the step. A wizard is launched to execute the step. The activity has already made some selections in the wizard. Some of the selections made by the activity cannot be changed. Executing steps individually gives you the maximum amount of control over the options in the step.

If you run one or more steps individually, you can run the remaining steps in the activity by clicking Run Activity just above the list of steps.

To reset a step, click Restart; all steps after that step are automatically reset. You can then change options if necessary and execute all succeeding steps or execute the steps individually.
