Re: glad to hear

is there a time frame for the next release? Is it possible to get a preview?

We'll be testing modified EM for couple of days. If it works OK we'll release GeNIe or at least notify you and provide link to preview version.

As for the crashes - the software will crash when the input network has a ...

The code I have at the moment is:

probmatrix = theNet.GetNode(disthandle)->Definition()->GetMatrix();
int count = (probmatrix->GetSize())/NUM_GAITS;
int n=0; double probs[NUM_GAITS][count];


I don't think this will compile. You'll need constant expression as array dimension; the 'count ...

Re: not randomizing the parameters

I will also mention that after a couple of dozen training sessions Genei tends to become unstable, and I see problems in image rendering and a significant tendency to crash, mostly if I try to close the program.

Does this happen with small model you've attached in one of previous posts, or the ...

Re: Comparing the structure of 2 BNs

Can someone help me with this or provide a reference on a freely available tool or scripts for this type of analysis?

I don't know about any existing tool/script for such task. You'd have to write such program yourself in C++, Java or .NET. I can help with any specific questions asked on this ...

Did you try the most recent build (2.0.3393.0)?

The 'unobserved state' is the way for SMILEarn to deal with data column containing only one value. SMILE's discrete nodes can have two or more outcomes and SMILearn must follow that constraint.

No, your best bet is try to run GeNIe under WINE emulation layer.

Ok, I answer myself :) I've made the following function:

But if you want to use entry in the dataset as a parameter when calling SetEvidence, you should do the lookup in the other direction:

1) get the integer value from the dataset
2) use that value as an index to obtain the string from ...

Hi,

If I've the following file:
NO
YES
YES
NO

And I make read file, the state 0 will be NO and YES will be state 1,
but if you make in different order this will change.

Just to clarify things, the order should not change. If dataset column contains non-numbers, they will be sorted ...

Re: Influence Diagrams in dynamic networks?

Dynamic IDs are not supported at this point. GeNIe shouldn't allow the creation of utility nodes in temporal plate, so in fact you've found the bug :)

Re: K-Fold Crossvalidation

But first of all, I was thinking it has overloaded the = operator so it will not be a pointer to the same data, but it's not so after deleting from each dataset it's deleting from the others :(

Thanks for reporting that issue. Technically what's missing is the copy constructor; the default one ...
