Re: Most determinant nodes

Thanks for the suggestion, but strength of influence does not capture what I need (that is, understand the most influential variables on my target node, and somehow quantify this influence).

Most determinant nodes

Hi,

Is there an option (GeNIe or smile) to understand what are the most determinant factors/nodes of my BN? and to somehow quantify the size of the effect they generate?

Thanks!

cross validation

Is there a possibility to view the individual results of each fold of a K-fold CV?
Also, how is the final result for K-fold CV calculated? average of K folds? min of the K folds? max of the K folds?

Thanks

piechart

Hi,

Is there an option to replace the counts on the side of the piechart with percentages?

Thanks

visualization and business vs academic version

Hi, I was not sure whether this question should go to the forum or to your email directly. If you would like me to move it to the forum, please say so. I have been using the academic version for a while. My problem is when I try to visualize my networks in order to include pictures of them in my pap...

pysmile k-fold CV

Hi, Just started using pysmile (was using only GeNle so far, but reached to a point where I need some bigger scale network). I have two questions and will be very grateful if you can answer : 1. I am trying to understand how to perform a simple k-fold CV in pysmile. This topic is not included in the...

Re: "observed" continuous node, modelling logistic cpd

Let me rephrase: are there any observed and continuous nodes in GeNIe that can integrate with chance nodes in the sense that they can have choice nodes as descendents? For example, the equation node can be cont. and observed but it can not have a chance node as child. (Almost all my network is built...

Re: "observed" continuous node, modelling logistic cpd

Hi-

Thanks, but I am not sure I understand: how can I represent my weights using nodes (which is what I offered --- a weight corresponds to a node) if there is no option for a node that can be both observed and take a continuous value? (or maybe there is?)

Thanks!

"observed" continuous node, modelling logistic cpd

Hi, I am trying to model a logistic cpd with the GeNIe. As it does not offer such a built in mechanism, I obtained the weights from another source. My problem is now how to build this cpd using the building blocks GeNIe offers. I was planning to use the equation node for the softmax, and "abuse" a c...

missing values in test data

Hi,

How does GeNle deal with missing values of observed nodes in the test (validation) data? (I refer to the option of "test only", not to CV.)

Thanks!

Re: logistic-cpd nodes

Hi-

Regarding 2.: I do have missing values in the training data for some of the nodes. I also have latent nodes for which I do not have any training data at all. I this a problem? I thought that since you use EM it should not be..

logistic-cpd nodes

Hi, First, thank you for answering my previous questions! 1. I want to combine one node with a multi-valued logistic cpd (sigmoid) in my network. I did see that you have the option of an "equation" node but I am not sure how do I need to use it to achieve a multi-valued logistic cpd. For example-I w...

changing the cutoff

Hi,

I am doing a 3-class classification problem.
From the ROC I figured that I need to change the cutoffs. How can I do that in the software?

In general, what are the cutoffs the software uses for a 3-class classification?

Thanks!

mac version and other questions

Hi, I am using the GeNIe academic (bayesian networks) and have some questions: 1. Is there a mac version for that? I am currently working with the windows version on a VM and it is slow and very inconvenient. 2. When I choose the "validate" option, and test my network on a data file, how can I see t...
