General Discussion / Re: Expressing Fault Tree Analysis in BBN

« on: June 06, 2018, 07:09:52  »

Hi Mel,

The "generalization" of OR / AND is MAX / MIN. If you encode false/correct as 0, true/failure as 1, and defective as 2 using Numbered nodes and use MIN/MAX instead of AND/OR, then you should be able to encode the desired CPTs.

The idea is that there must be an order on the states and this is enforced by the use of the Numbered node where 0 would reflect the absence of a cause and higher values reflect a more significant presence of the cause.

Let me know if this works for you.

FAQ / Re: How can I use HUGIN in Matlab?

« on: May 16, 2018, 10:00:09  »

The method

Code: [Select]

enterFindingis used for entering evidence on a node. There is also a selectState method to set the node to a specific state.

To change the CPT of the a node you need access the table for the node and manipulate its content. The documentation has a complete example building a network (here referring to the .NET API documentation):

Is it possible to assign multiple nodes into an array in MATLAB and then call them from there instead of "one-by-one" method?

Yes, this should not be a problem. I'm not certain of the exact syntex, but using the HUGIN .NET API it should be something like this:

Code: [Select]

Node []array;
array = new Node[2];
array[0]=A;
array[1]=B;
hope this helps

Hello,

If you want P(C1=true|P2=true,P3=true)=0.3*0.3=0.09, then you can achieve this using a "noisy-add" gate as demonstrated in the attached model. You set P2_input=true and P3_input=true to get the desire result.

Hope this helps.

Hello,

This line of code is not correct:

Code: [Select]

A_table=d.GetTable ('A');
You should invoke GetTable on A as in:

Code: [Select]

A_table=A.GetTable ();
The node A has a table (a representation of its CPT).

hope this helps

Hi,

Domain does not have a table. You need to access the node. Can you send the code that produces the error?

C# / Re: Run-time error 429: Active X component can't create object

Hi Olivia,

Good to hear from you.

It seems like the HUGIN version and MS Excel version are misaligned. You need to make sure that both are either 32-bit or 64-bit. They cannot be mixed.

If your MS Excel is 32-bit, then you need to use HUGIN Deverloper 32-bit. You should be able to install HUGIN Developer 32-bit next to your 64-bit. They should not conflict.

Hope this helps.

Hello,

Any chance that you can send me the network file and the file you are trying to import? Then, we can find the cause of the problem.

Hi Marco,

No, unfortunately, I do not know of any conversion tool. How many and how complex are the models you need to convert? I'm assuming you are converting from Netica to HUGIN.

Best regards

Did you actually read this: http://forum.hugin.com/index.php?topic=259.msg645#msg645:

Our HUGIN is a tool for probabilistic graphical models  (see www.hugin.com) and does not support such operations.

Perhaps you are looking for the open source Panorama photo stitcher (with which we are not affiliated)
http://hugin.sourceforge.net/

There is a mailing list for this and similar programs at:
