DBN support is a great addition to the software. I do however have the following question/issue. I have a network, part of which contains the nodes: A (Initial/Anchor) B (Temporal) with the following links: A->B B->B (order 2) When I come to specify the network parameters for node B, I only get dis...

If I built a network that is not an influence diagram can I make the sensitivity analysis with the addition of a Decision node "Sensitivity" as explained in the Tutorial 12? Thank you very much! Yes, you can. Just add a decision node along the same lines as in the tutorial, update the net...

What is exactly a 'target node'? Is simply the variable you are interested in or is necessary that it has specific properties (e.g. could be performed a diagnosis test on this variable)? Well, it depends where it is -- have used this name somewhat inconsistently :-). In case of sensitivity analysis...

1. Scalability - you have described it is a function of the network topology kind of evidence etc. But when working with say, thousands of variables, are there any best practices/guidelines to follow? how would one go about optimizing the model for scalability 2. Parallelism - Can we parallelize th...

A Americans say, "The proof is in the pudding" -- the ultimate performance of your system is the best way of verifying it. I think a scenario work-through would be one simple method. Take a few imagined cases of users who should be interrupted (accodring to your expert) and see whether you...

You need to tell us more :-). Have you built the network based on data or on expert knowledge? If on data, you can use part of the data to learn the network and a part to validate it -- this is called cross-validation. If it is based purely on expert knowledge, there are many techniques that you can...

Therefore the sensitivity tool is kind of one-way sensitivity analysis were each parameter is variated separately, is it correct? For 'tha tables for sensitivity mode' you mean Max Min Avg in the balloon containing information about Sensitivity? This is correct -- it is one-way sensitivity analysis...

Hi all, I have a naive question :( I have an influence diagram matching a real-world experiment. This diagram has only one utility node, and in the experiment I can observe the value corresponding to this utility node. Since the utility node maps utility value to the values in the parents node in t...

I am a GeNIe new user. I built a network and now I would like to do the sensitivity analysis using the sensitivity tool. I tried it but I didn't understand how it works. I found the Helps information too general instead the reference paper too difficult (sorry, I am not a statistician :oops: ). Cou...

I am looking for the algorithm Genie is using to compute the relevancy of observations in test view. Thanks We use a simple algorithm that computes the expected gain in cross-entropy between the target fault and the observation. One place where you will find more information about the algorithms ap...
