Re: doubt for learning new network

But when I conduct the discretized process of Hierarchical / Uniform-Width with learning method such as Essential graph search / PC with the same data file, there is no response and then the GeNie program is automatically closed. Could u pls explain why? GeNIe closing without any error message sugg...

You should set some evidence on observation nodes marked as mandatory before performing the diagnosis (with DSL_nodeValue::SetEvidence in C++ or with Network.SetEvidence in .NET).

Can you remove the 'mandatory' attribute from Error_105 and check what happens then?

Re: diagnosis network functions in GeNie / SMILE

Can you post the actual network (not just the screenshot) here?

There are two parameters for controlling EM algorithm: 1) 'confidence level'. It's described in the dialog box shown after matching network and data and before running EM; see this thread for more information: http://genie.sis.pitt.edu/forum/viewtopic.php?t=4 2) 'randomize initial parameters' - this...

The naive Bayes algorithm can't be applied in your case - it creates simple model with arcs directed from 'class node' into all other nodes. Since you're interested in structure where arcs go into specified node (Off_Alw_Fo), the PC algorithm should work. In fact, you've obtained the model which is ...

Re: [.NET]libary for .NET compact framework

Would you please to provide library .NET compact framework? Already having a library for .NET framework, is it hard job to convert .NET framework to .NET compact framework? I don't know - we don't have any experience with .NET CF. You're the first user asking for support on this platform. While we'...

Re: Bugs with decision nodes as parents of nature nodes

It appears that there is a bug with decision nodes as parent of nature nodes in the Smile engine. Please import the following Netica file to see the bug. The file loads OK with the following warning messages logged (despite the 'ERROR' prefix, they're just warnings): (line 13) : ERROR: 'NodeMaxNumE...

Re: network width/height

Is there a way to find network boundaries (i.e. maxX and maxY)? Iterate over the nodes, retrieve the position of each node and create the union rectangle. If you're using C++, then you could use DSL_network::SimpleGraphLayout after adding the nodes at any position. This would use parent ordering to...

Re: problems building networks based on a database

I'm not sure what exactly is your problem. Did you used automatic translator? If so, please ask somebody who knows English to translate for you.
