FAQ / CLI install documentation HUGIN 8.7

« on: October 18, 2019, 09:59:10  »

The following command-line is known to work (April 2019):

msiexec /i HuginDist87(x64).msi /L*v SilentInstallation.log /quiet PATH_LICENSE="C:\TMP\LICENSE-8.7"

A couple of words on the installation:

• The PATH_LICENSE is of course the path to the location of the HUGIN License file.
• The .MSI file does not perform a cryptographic check of the License Key - only a shallow sanity check. The deep check is performed every time HUGIN is launched. Therefore you must launch HUGIN to be sure that everything is working properly.
• The .MSI file will write the license to the location: C:\ProgramData\Hugin Expert. If anything goes wrong, the file can be manually copied to this location.

Dear Marco,

The number of time slices is set under "Network->Network Properties->DBN".

Hope this helps

Hello Raymond,

I assume that you by now have realised that "our" HUGIN is a tool for probabilistic graphical models and not images.

Sorry for the belated reply.

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.
Anders

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

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?

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.
