Hi Arsham,

This article should give you an overview of the background of tornado diagrams

Hi,

The Equivalent Sample Size influences the structure score and is a part of the BDeu calculation, it's sort of represents an inertia of the current parameters when introducing new data.

It is not related to the number of samples in your dataset.

Hi, These are the parameters that are used for the Bayesian Search algorithm, and I've listed if they influence the score or not (i.e. if the same structure obtained under different parameter settings would result in a different score) Max Parent Count - Limits parents of a node, has no effect on th...

Whoops, my bad.

Hi Ralph,

It's kept after it's created and is reused for later inferences.

Hi Nordic,

We've tracked down a bug causing your problem and have fixed it.
We've updated the GeNIe installer on our downloads page.

After reinstalling everything should be fine.

Best,

Hi Peter, The filter function is not for filtering variables but for filtering records. If you want to select a subset of variables I recommend making a copy of the dataset and then removing the variables you are not interested in. If I remember correctly, this is how GeNIe does it under the hood fo...

Hi Nordic,

It seems your training data is missing, could you repost it.
I'll have a look. I implemented the code responsible for converting patterns into DAGs.
Both GeNIe and SMILE should be using the same code.

Martijn

Could you perhaps tell me a bit more about DBN.o and DBNLearner.o?
How were they compiled?
These are from code that you've written?

Martijn

I've seen that typo before, it's tutorial code.

What does your main code look like Peter?

Hi Bernt, For Bayesian networks we assume Multinomial distributions. Yes, the log value is the loglikelihood of the data, i.e. how well the model fits the data. As long as your data does not contain any missing values the EM algorithm works the same as the same Maximum Likelihood Estimation. If ther...

Hi

In the end, it doesn't make a difference unless you are interested in the intermediate probabilities after setting evidence one by one.
With either method 1 or 2 , if you check the posteriors of the variables after setting all evidence the result is the same.

Hi Nordic,

No, there currently isn't any.

Hi Bernt, What you want to change is the following line: DSL_sysCoordinates theCoordinates (*theNet.GetNode(mL)->Definition()); Here you are looking at the definition and not the value after updating. It makes sense it's 1.0 because the node is deterministic. Try: DSL_sysCoordinates theCoordinates (...

It seems this might be a more general problem, i.e. how to link to a c++ library from xcode. So it's not really an issue related to smile. You may want to search the web for some instructions. I did a quick google search and I found a few already: http://stackoverflow.com/questions/8950388/link-obje...
