Re: How to avoid error -42 in UpdateBeliefs in jSMILE

Thanks for your help,
I've found out that approximate inference helps, but I'd like to only have to use it when exact inference fails. I've written the following code to do that:


final static int[] ALGOS = { // Algorithms to try, in order.
//Network.BayesianAlgorithmType.Lauritzen,
Network ...

How to avoid error -42 in UpdateBeliefs in jSMILE

Hi,

I'm working with a network of a little less than couple hundred nodes, all of them discrete CPTs, and in my code I need to compute probabilities of the form P(X|Y) many times where Y isn't always a parent of X.

I do this by doing

net.clearAllEvidence();
net.clearAllTargets();
net.setEvidence ...

Re: DeleteNode Behavior

Thanks, that answers my question.

The probabilities managed by SMILE are always consistent.
By "consistent" you mean summing to 1?
I was being too vague in my last post: what I meant by "consistent" is whether P(B=1) in the resulting network will be the same as P(B=1) in the original.
Based on ...

DeleteNode Behavior

Hello,

I'm using jSMILE so this will be in Java notation but I imagine that this is language-independent.

Suppose I have a network (of discrete CPDs) where A --> B. What happens to the CPD of B when A is deleted by calling network.deleteNode( A's handle )? It doesn't seem to be documented ...
