Hello,

I have a question regarding the ROC/AUC calculation in GeNIe for binary classification.

For a binary node, GeNIe reports a separate ROC curve and AUC for each state. For example:

Example using the standard ALARM network and 1000 simulated cases, node "Disconnect" (states True/False ...

Hello,
thank you for the fast reply!

Regarding the Hosmer-Lemeshow test, I have a question about the binning mode.

How are the observations assigned to the groups used for the Hosmer-Lemeshow calculation? Are they separated into equal-width bins over the interval [0,1], or into quantile-based ...

Hello,
for the calibration plot in GeNIe I saw that binning can be used.
I just want to make sure I understand it correctly.

Am I right that the probability interval [0,1] is divided into equally sized bins, and for each bin the plotted value corresponds to the mean observed frequency of the ...

Hey Marek,

thanks for the quick reply!

While experimenting, I noticed that after learning with EM in GeNIe I never end up with hard probabilities like exactly 0 or 1.

That made me wonder whether GeNIe might implicitly avoid zero probabilities, since hard 0/1 values can cause issues during ...

Hi GeNIe- Team,

while experimenting with the EM algorithm (Uniformize/ Randomize) in GeNIe, I noticed that a smoothing mechanism seems to be applied.
Is it possible to clarify what kind of smoothing or pseudocounts are used?

Thank you in advance.
