Hi,
I would like to know as to what is the convergence criteria that is being used in GeNIe to learn the parameters using an EM algorithm.

My qns.
1. Is it just fixed to a large no. so the algorithm runs for so many no. of iterations or some other criteria? How do i change this criteria if needed ...

Thanks. That helps.

Thanks for letting me know.

Is my understanding that GeNIe uses an EM algorithm to compute CPTs correct?? If yes, can you let me know as to which EM algorithm does it exactly use, I mean there are other modified Em algorithms like Voting EM etc as well.

Also how many records do we need to have ...

By learning rate, I mean the eta value used by the algorithm to calculate the CPT table parameters. From the attached paper, I got the formula (Eqn 6) which I am using to calculate manually the CPT table values for 2 records data-set. But when I try learning in Genie the answers do not match up ...

Hi,
I am a newbie to Genie and have been learning the tutorials given. I am trying to learn parameters for the alarm-burglary network (attached) with 2 hypothetically created dataset (attached). When I Learn parameters, Genie says it is successfully learnt and gives me a resultant network with CPT ...
