Creating or Modifying Build Tasks

The first step in the data mining process is to build and train a model to apply to a set of data in the database. The task of building a model includes the following steps:

Note:

Before launching Mining Wizard, be certain that the database has been loaded and calculated.

After you build a model, you can test the model by applying it to a known set of data, or you can generate results of interest by applying the model to a new set of data.

  To build or modify a mining model using Mining Wizard:

  1. Select File, then Wizards, and then Data Mining Wizard to launch Mining Wizard.

  2. Select the server computer, the application, and the database to use, and click Next.

  3. If Advanced mode is desired, select Advanced, then complete one of the following actions:

    • Select Create a New Build Task, click Next, and go to Step 4.

    • Select Modify a Saved build Task, click Next, and go to Step 5.

  4. If you are creating a task, from the list of algorithms, select an algorithm to use, and click Next. Go to step 6.

  5. If you are modifying a build task, from the list of build task templates, select a template, and click Next.

  6. In the left pane of the Enter Values for Algorithm Page, expand all nodes and complete the following steps:

    1. If you want to change the default setting (Skip missing values) for how the algorithm handles missing values, select Choose mining task settings, and, in the right-hand pane, change the setting.

    2. Select Specify parameter values for the task to set parameters for the algorithm.

    3. Select to open each of the remaining nodes (Define Predictor, possibly Define Target, and so on), select each accessor in turn and type a MDX expression for each required domain and, as desired, for any optional domain.

    4. Click Next.

  7. Select Save and execute mining task, Save mining task, or Execute mining task.

    If you select Execute mining task or Save and execute mining task, enter the Mining Model Name and, if desired, a Mining Model Comment.

  8. Click Finish to execute the task and/or save the task template.

To view the progress of the build task execution, in Enterprise View, expand the Data Mining node, right click Mining Sessions, and select Display Mining Sessions.
