EM Learning Wizard

To get assistance in the process of learning the CPT's of a Bayesian network from data, the EM Learning Wizard can be quite useful.  The EM Learning Wizard can be invoked from the "Wizards" item of the menu bar of the Main Window.

Please note that the EM Learning Wizard is intended in situations where a network structure is already available. If a network structure is not available, one should consider using the complete Learning Wizard, which provides a superset of the functionalities provided by the EM Learning Wizard.

The EM Learning Wizard can read data either from a plain text file or from a database, and it allows preprocessing of the data in different ways (e.g., variable exclusion, value replacements, and discretization) and to provide prior knowledge about the conditional probability distributions.

Please note that the EM Learning Wizard allows external data preprocessing plug-ins.

For more detailed information on the EM Learning Wizard, please consult the online help pages provided with the EM Learning Wizard.
