Re: SMILE source code

Pete,

We have considered making GeNIe and SMILE open source and discussed internally arguments for and against, doing some research as well. We have finally decided against it. So, compiled version only :-).
Cheers,

Marek

Re: node->Info().Screen().color returns wrong RGB String

We've added this to the Issue Tracker and will have a look at this in the near future. Because it is not a critical issue, please do have some patience with us here.

Yes, this is correct -- the documentation refers to Murphy's thesis. Cheers -- Marek

Re: JSMILE - GPL compatibility

The way I read your question, it is about legal issues, i.e., what happens when you include jSMILE code into code that is covered by the GPL license. I'm afraid I don't know the answer to that question. While we are making our programs and some source code (like jSMILE) available free of charge, all ...

Re: Equation Node Documentation?

When we want to model an equation node that changes in the time, how can we introduce time variable in the node equation!!
:(

I'm afraid we don't support that (yet :-)). You could, of course, have an explicit variable "time" in your model and use this variable in equations. That variable would ...

Re: Confidence/credible intervals?

Doesn't this rely entirely on the model, which is often subjective anyway? What is the meaning of the confidence interval in this case? That the modeler is, say, 95% confident that the posterior is within the calculated bounds? I'm curious how you calculate the confidence interval for single ...

Re: epidemiology, case-control studies

Angelo, I'm not aware of any applications of GeNIe in epidemiology (we are not monitoring what GeNIe users are doing), although this does not mean that there are none. In fact, Google Scholar search on "Bayesian networks", epidemiology and "case studies" yields quite a number of hits. Because GeNIe ...

Re: How is soft evidence implemented in SMILE?

Hi Ronnie,

First of all, I woul dlike to appologize -- SMILE and GeNIe implement "virtual" and not "soft" evidence. I have understood the difference after we have added this functionality SMILE. We are actually planning to add "soft evidence". Our implementation of virtual evidence is by adding a ...

This doesn't actually give me what I want. What I would like is the expected value of the optimal decision at the decision node, when that decision is made using the information from the chance node.

Do you know if there's an easy way to calculate that in GeNIe, without adding a prior decision ...

Re: Influence diagrams and Diagnosis

why its not allowed to use nodes from influence-diagrams like utility/decision nodes in the diagnosis-tool?
Is it just not yet implemented to use this nodes in diagnosis now or is there a special conceptional or mathematical reason not to allow these node types?

Influence diagrams do not need ...

Soft vs. virtual evidence

GeNIe implements what is called "virtual evidence," which is uncertain observation that will propagate through the network. Virtual evidence can be (and actually is in SMILE and GeNIe) implemented by just adding a dummy child node and making sure that the CPT of that dummy node results in sending ...
