Re: Loopy Belief Propagation
Have you any experience with residual belief propagation? Does it converge to a solution on networks where synchronous loopy belief propagation starts to oscillate?

Re: Loopy Belief Propagation
In Java the BayesAlgorithmType has a public static final int LBP = 9; which must be Loopy Belief Propagation if you say that it is supported. How do you set iteration count and damping?

Loopy Belief Propagation
Hi!
Is it possible to select pure loopy belief propagation as algorithm even if it is not correct, only to see its result?

Re: QMR style net crashes
I already thought of this possibility that you calculate with the "unrolled" CPTs. So at first I can continue with my own loopy belief propagation and then see if I can verify the result by setting the nodes with highest probability as targets in SMILE. Maybe loopy belief propagation is al...

Re: QMR style net crashes
Maybe some nodes have too many parents. If I restrict parent count (e.g. to 3 as a first test) it works. for parent count restricted to 20 it starts to fail. Interesting is that Likelihood Sampling takes very long but terminates, but EPIS-Sampling crashes after some time. I wonder why this is so bec...

QMR style net crashes
Hi!
I have a QMR style test network. It can be loaded, but when evaluating it it crashes. I tested different algorithms. Do you want to have a look at it?
For some reason I can't attach the file, it always says that it is empty. The zipped version is 33kb. Can I send it by mail?

Re: How to set algorithm with Java API
I found it: I forgot to reverse the order of the parents for CPT nodes. I organize CPTs in own states, first parent to last parent states while smile organizes CPTs in own states, last parent to first parent states.

How to set algorithm with Java API
I have a very simple network (rain, sprinkler, holmes, watson, see attached file). This works perfectly in the gui (genie), but using the java api the results are quite imprecise. In the gui I have the default settings for algorithm (Clustering, Policy Evaluation, Hybrid LW). In Java I tried the opt...

Re: How to set output order of noisy max
Hi Adam, in the properties dialog for noisy max I discovered an outcome order selection which allows none, low to high and high to low. This looks like what I'm searching for, but it does not seem to have an effect, also the possibility to set none is strange as only low to high and high to low make...

Re: How to set output order of noisy max
So is it necessary that the noisy max always sees the distinguished state as last state (highest id)? I would think this is theoretically not necessary, but is it necessary for the implemented algorithms? I can remember that there are special optimizations possible that exploit the noisy max disting...

Re: How to set output order of noisy max
Thanks for your answer. The problem arises when converting a network description to a SMILE network. I will reorder the states, i.e. if the output of a noisy max is fed into another node the cpt of the other node is reordered for the noisy max parent so that it reflects the actual order used by SMIL...

how to use noisy adder
I'd like to test the noisy adder, also known as noisy average in the thesis of zagorecki (Local Probability Distributions in Bayesian Networks: Knowledge Elicitation and Inference). I use this code to create the pump example: Network network = new Network(); int pump = network.addNode(Network.NodeTy...

How to set output order of noisy max
Hi! I'd like to define nodes with outcome id 0 for false and outcome id 1 for true. When two of these nodes are the parents of a noisy max node, I have to set the parent strengths to [1 0]. The noisy max node has the convenient setNoisyParentStrengths method (java) to do this. But how do I set the s...
