Is it possible to limit the number of arrows...?
« on: November 17, 2015, 10:45:00 »
Hi,

I am trying to find a way with Hugin to limit the number of arrows directed towards a node or originated from a node.

At the moment I can't find any indication in this sense but I would like to be sure of that.

Thanks

Alessandro

There are no limits on the numbers of parents and children.

What is the reason for this question?  Is it related to structure learning?

Thank you for the reply.

I was just wondering if during the structure learning process it was possible to simplify the BN by introducing a constraint in order to reduce the number of arrows connecting the nodes.

It is possible to specify a limit on the number of parents for the greedy search-and-score structure learning algorithm.

Alternatively, you can consider using structure restricted models such as, e.g., the tree-augmented naive Bayes model.
