Netica can learn the CPTs of nodes directly from cases stored in an Excel spreadsheet (aka workbook). Described elsewhere is Netica’s ability to learn from text files of cases, and Netica’s ability to link with Excel to export posterior beliefs.
Here are the steps to learn a Bayes net directly from an Excel spreadsheet:
1. Create an Excel Spreadsheet
3. Discretize or Combine States
5. Learn CPTs
6. Use the Resulting Bayes Net
Note: If
you are using Netica on a Mac, learning
from an Excel file will not work. You must convert your case file
into a text
file and then you can proceed with the steps listed above.
