I implemented the above, and im getting a bunch of these messages,
-26: EM: can't set evidence in record 3 for node NODE040
-26: EM: can't set evidence in record 8 for node NODE040
-26: EM: can't set evidence in record 17 for node NODE040
-26: EM: can't set evidence in record 29 for node NODE022

Okay, thank you for the elaboration I know how to proceed now.

Thank you so much for this information. In the em file I generated CPTs randomly but looks like because some of the values were so close to one or zero they got rounded up/down. Would you recommend using "em.SetRandomizeParameters(True); " instead of passing in the initialization through a file ...

I am using Smile (the C++ version) Here is my code for the EM portion:


std::vector<DSL_datasetMatch> matching;
DSL_network emModel;
DSL_dataset ds;
double loglik;

//reading data file
res = ds.ReadFile(dataFile.c_str());
if (DSL_OKAY != res)
{
return res;
}
//passing in the initialization for ...

Hi, I attached some of the files. ex7_TD2_10.xdsl is the model file. ex7_TD2_10.csv is the data file. and em_ex7_TD2_10_ED2_0.xdsl is an initialization for the em algorithm, which gives me 8.29714e-318 as a log likelihood

I keep getting this value 8.29714e-318 as a loglikelihood while running EM. Im running EM on discrete bayesian networks, so therefore the LL should be between [-inf, 0], but 8.29714e-318 keeps showing up within multiple runs of EM, even on different networks. Can someone explain why this is happening?

I know the log likelihood is calculated with in the EM and other learning algorithms, but does there exist a function that takes an existing network and a dataset, then calculates the log likelihood sore, without necessarily learning parameters?

If not can you tell me how the log likelihood is ...

Thank you so much I will update

Hi it looks like its still only pulling the 1.6.2 version of pysmile. Copy and pasted below is my terminal output

$ python3 -m pip install --user --upgrade --force-reinstall --index-url https://support.bayesfusion.com/pysmile-A/ pysmile
Looking in indexes: https://support.bayesfusion.com/pysmile-A ...

I deleted my old version of smile, and used the command "python3 -m pip install --index-url https://support.bayesfusion.com/pysmile-A/ pysmile". However, I checked the folder in in my python packages, and the package shows as "pysmile-1.6.2.dist-info " which i don't believe is the latest version ? I ...

Can't read in some of the model files from the bayesfusion repo.
Im using the python wrapper of smile.

Code:
net = pysmile.Network()
net.read_file("test_new_models/HeparII.xdsl")

error:
SMILEException: SMILE Error Occured in: Network.ReadFile
