Greedily adding means that it adds (or reverses) the edge that increases the score as much as possible. This process is repeated until there is no operation that increases the score anymore. In the second stage it removes (or reverses) edges that, again, increase the score as much as possible. Learn...

Does this answer your question? http://genie.sis.pitt.edu/forum/viewtopic.php?t=182

I think I found the problem. Instead of just using integers in the data set, prepend them with 'State_' so that the exact state names from the network are matched. That should work.

There should be no small sample correction. Is all the data complete? Would you mind sharing your network and data?

I found the cause and solution of the 'em: not all nodes are updated (deterministic cpts?)' error message. This should be fixed in the next GeNIe/SMILE release.

Are you randomizing the initial parameters?

It should never crash. Could you share your network and data set so that I can reproduce the crash? The error message you were getting could be due to insufficient records, how many were you using?

Do you have missing data?

Are you sure that handle 0 in the network corresponds to the first column in the data set? And similarly, for the other handles? Handle 0 could refer to a different variable in the network than the variable name in the first column of the data set, and it's not obvious to me that they match.

Obviously, you should be able to get the same values in SMILE that you get in GeNIe. To judge what is going wrong, I need some more code and the data and network as well. Are you sure you are setting the evidence correctly?

Is it possible that you're not doing anything wrong, but the predictions you're making are simply imperfect? Please note that the correct value for the target node is 0 or 1, but that you will not obtain these values after performing inference (you'll get a probability distribution). Also, why are y...

You're right in that you cannot set evidence for a utility node, so you'll have to change the utility function by changing the parameters of the utility node.

Yes, that was the problem.

No, not at the moment.

A1. Correct, .neta is a binary format and not supported.

A2. I don't know exactly, but at least the basics should work. I don't see the file you attached, so can you re-attach it or send it in a personal message?
