How to update prior distribution with likelihood distribution

[jshen132]

Hi all,

How can you update a prior distribution defined in the CPTs in GeNIe with a new set of data (likelihood distribution)? Is it possible or is it only able to in pre-processing?

Thanks in advance

You should run EM parameter learning using your dataset. Ensure that parameter initialization option is set to "Keep original" if you want to use your new data as an additional source of information over the existing network.

For more information, refer to the "Learning Parameters" chapter in GeNIe manual. You can access the manual from GeNIe's Help menu, or as PDF and HTML versions at https://support.bayesfusion.com/docs/

Hi Shootlz, thanks for the fast response. When I select Learning>Learn parameters... I get an error that "There are no data files open." The manual doesn't exactly match the version (GeNIe 4.1) I have downloaded. Do you know how to address this error?
