Re: Most determinant nodes
I think the suggestions of sensitivity analysis is the correct choice.

Re: unbalanced data and parameter learning
Hey Marek, Thanks a lot for your suggestions! About the " prior probabilities of classes will not reflect the frequencies in the test data", I think that is a really good point to consider. The prior probability of selected class (two state) does changed after balancing, but the joint dist...

Re: penalize parameter for accuracy
Hi Marek, thanks for your suggestions!
I will check the eneral machine learning literature on unbalanced data sets.

unbalanced data and parameter learning
Hello! I am looking for suggestions of dealing with unbalanced data. When I conducting the validation, if the selected class has two variables,state 1 and state 0, the accuracy of each state is 0.33 and 0.90, due to the unbalanced dataset (much more state 0 than state The model shows the total accur...

Re: penalize parameter for accuracy
Hi Marek, thanks for your swift reply! I learned how to changed the threshold now. May I ask more questions? 1. When doing the validation, if the selected class has two variables,state 1 and state 0, the accuracy of each state is 0.33 and 0.90, due to the unbalanced dataset (much more state 0 than s...

penalize parameter for accuracy
Hello, I am new to GeNIe. I am writing to ask the method to change the penalize parameter for the prediction accuracy. e.g. the predict outcome has two state, when building the model or making validation, the accuracy is the total prediction accuracy of the two state(usually one state is low and one...
