Parameter Learning
« on: May 19, 2023, 18:25:58 »
I have a rather large model built (using structure learning in Hugin) using a large dataset.  I would like to use the same structural model with different data.  For this particular case, I would like to ignore all parameter values learnt from the large dataset.  EM learning starting from the structure with all 1s in the CPTs and zero experience counts seems to be the way to do it, but I do not want to manually replace all experience counts with zero and all entries in the CPTs with 1.  Is there a way to reset CPT entries in bulk?

Hi Marco,
You can run the EM learning Wizard that has the option to reset all tables and all experience counts.
