ahh, okay, I understand.

So if I would use a 64bit Windows it should work with a bigger network?

Genie crashes if Probability table gets over 4.X million

Hello,

I have the following problem.

10 Nodes, each 5 states. Now connecting Node1 to Node9 to Node0. So the probability table should be 9 Million. Then GeNIe crashes :-(

Is there a limit of possible propability values? How can I get beyond this limit?

Thank you,

Christian

As I need the continuous variables, is it the same to just define one node (the one that I consider to be the continuos Variable) and set the percent value directly? For example: I want a continuous variable with 60%. Do I have to set value (state0) to 60% and "antivalue"(state1) to 40%? I...

Thank you Mark for your reply. You helped me a lot so far. Yet I have not tried to average the training results as it is very complicated to do this manually. I will need to write a programm for that and yet I am not so far. But it is something I will do. Or is there a way to do the averaging automa...

Yes this is working now! Thank you very much! The only thing that is left is the following: Learn WetGrass_sprinkler_cloudy.txt Learn WetGrass_rain_cloudy.txt Everything is good so far. Learn WetGrass_wetgrass_sprinkler_rain.txt The Node wetgrass ist correct, but the node sprinkler and the node rain...

Hmm. It really seems that this version is buggy. But only when importing partial data. While importing complete data is working fine. Do you know if the odbc connection uses the same import way for partial data or could I import my partial data into the database first and import it then using the od...

Hello,

my Version is 2.0.2811.0 built on 09/12/2007. I got the latest windows version from the homepage.

Then this should be a bug, I think.

Are you using Windows or Linux?

Hello Mark, So, summarizing, when you generated data for just 2 out of the 4 variables (e.g., Cloudy and Sprinkler), and I assume the data for the 2 variables was complete, the results were not as good as was the case when you used counts. Just training cloudy sprinkler or cloudy rain was not ok. Tr...

Continuous variables

Hello, I found in the tutorial an explaination about "Continuous variables". Is it possible to use these in GeNIe? As I found no way to set a chance - node to a "Continuous" one. I only can set true or false. Maybe if that is possible I could also set something like 40% true, 60%...

Re: Learning Parameters Confidence level

I don't think learning with the same data, but different confidence levels, is going to give better results. Why do you think so? It thought if given the fact that there is no expert data available we yould use a very low confidence level. After that we have the weights in the right direction. Now ...

I made some tests using the following Network: http://www.codeproject.com/cs/algorithms/BeliefNet/WetGrass.gif First I created exactly the same network. After that I used the Option to generate a data file. A) I checked every 4 values for creation (Cloudy, Sprinkler, Rain, WetGrass) 1000 Data Rows B...

Learning Parameters Confidence level

Hello, Using GeNIe, what is the intervall for the confidence-level? Is it 0...10 or 0..100 or ...? Would it be better if I start with randomized Values and then train the network again and again with the same training data, but higher confidence level? Which values do you use by your experience? Tha...

Parameter Learning with not complete Datasets

Hello, I have a large Bayesian Network. Let say I have 10 chance Nodes N0-N9. Now I could train a dataset with x rows that have no missing fields in N0-N9. But this way I have not so much data. But I have many Datasets with only some node values filled in. For example: N0, N3,N5,N6 N0,N3,N4 ... and ...
