Re: Submodel - a question + a suggestion

The result: those relocated nodes just stay there in coexistence with the submodel node that previously represents them.
Dragging nodes between submodels works for me. See the attached animated gif; are you referring to some other drag'n'drop action?

Re: Help with Bayesian Modeling

The answer from the StackOverflow thread is correct; Smile.NET is a mixed mode DLL which contains both native Intel code and Microsoft Intermediate language. This type of DLL is not directly supported by Unity.

Re: Any idea to create a truncated distribution?

The TruncNormal distribution generates samples by drawing a normal sample specified by its two first arguments (mean, stddev), then compares it agains the third argument (the cutoff). If the value is greater than cutoff, the sample is accepted, otherwise the procedure is repeated. To avoid infinite ...

Re: A simple question

The Elicitate command opens the interactive chart where you can move the interval boundaries with a mouse. The CPT is then adjusted accordingly. Note that GeNIe does not store the discretized CPTs in the xdsl files - only the intervals. The CPTs are derived at runtime. We'll fix the GeNIe manual to ...

Re: Discretization problem

During the discretization process the CPTs for the equation nodes are derived by sampling. Some of these samples may fall outside of the bounds specified for the node. If the sample value is less than a lower node bound, it's rejected and a count of underflow samples is increased. If the sample valu...

Re: Any idea to create a truncated distribution?

I want to create a truncated distribution - e.g. a normal distribution N(5,1) be truncated at a threshold, say 3, so that there is no frequency of occurrence before the threshold (3). Making it bit more complex is that the threshold itself is stochastic subjected to a distribution (rather than a fi...

Re: User-defined PDF function

The CustomPDF function requires the x coordinates (the first half of function arguments) to be in increasing order. Your equations have descreasing x ordering.

Re: Hybrid model program

That is to say the network cannot contain any decision and value node. At this point we don't support the equation nodes in influence diagrams - it would require relatively large amount of work. Note that you can use expressions in MAU utility nodes, including expressions conditioned by decision pa...

Re: Problem with structure learning

I tried my dataset with GeNIe and Greedy Thick Thinning algorithm and it works pretty well
Your data file contains columns with missing values, which are not compatible with Greedy Thick Thinning. Unless you've switched to another data file, GeNIe should tell you about the problems with your data.

Re: Problem with structure learning

Naive Bayes algorithm needs to know which variable in your dataset is a class variable. In SMILE.NET you can specify the class variable by setting the NaiveBayes.ClassVariableId property. The class variable identifier should be matched by one of the variables in the dataset passed as a parameter to ...

Re: Problem with structure learning

How did you select the class variable? Using the opportunity I'd like to draw attention to the fact that Bayesian Search algorithm is ...

Re: Leading S in text

The leading S is added by GeNIe when you learn network from a data file, and the value in the data column contains non-alphanumeric characters and underscores, or starts with non-letter. I believe your data file had a NATURE column with "aceration open wound" value. The spaces between the words caus...
