Crash confirmed, we're looking into it now.

Re: error with log likelihood during EM
The messages you're getting show that your data is inconsistent with the parameters in the network. You have a bunch of deterministic nodes, and you're trying to input an impossible combination of evidence from the data file.

Re: error with log likelihood during EM
In the em file I generated CPTs randomly If you don't have any initial probability distribution for your model, just use EM's internal randomization (call em.SetRandomizeParameters(true), and optionally fix the random seed for the initial parameters with em.SetSeed before SetRandomizeParameters). D...

Re: error with log likelihood during EM
Your code will run fine when starting with ex7_TD2_10.xdsl. The log likelihood is around -990. If the model used is em_ex7_TD2_10_ED2_0.xdsl, the DSL_em::Learn will return DSL_ZERO_POTENTIAL, which is defined as -43. This is due to conflicting evidence in the dataset. Your code does not check for th...

Re: error with log likelihood during EM
We checked the log likelihood obtained after learning parameters with your files, and got values close to -1000 (in GeNIe and with a simple Python program.)
Maybe you did not create a proper matching between your network and data? Can you post your code fragment where you call EM?

Re: error with log likelihood during EM
Can you post your network and data file here, so we can reproduce the issue? Alternatively, send me a private message on the forum and attach the files (or provide a download link).

Re: ValueError: vector::reserve
The error is caused by C++ exception caught by code binding between core SMILE library and PySMILE. It's a memory issue. Are you running 32-bit or 64-bit Python?

Re: strange pattern
The 'Learn parameters' command only learns parameters, and works on the model structure already present. Are you referring to the output from the PC structure learning algorithm?I use the Learn parametres function

Re: max sensitivity Genie 2.4
The min/max/avg are calculated over sensitivities of all parameters in node's CPT. The sensitivity algorithm calculates a separate sensitivity value for each of the CPT entry for each target state of each target node. You can view per-parameter sensitivities in the node properties/definition when se...

Re: Calculating values in Python and returning them to pySMILE
One more thing: if your calculate_stress function returns a list of values sampled from unknown distribution, then you can try to fit your samples to a metalog distribution. GeNIe/SMILE support Metalog since GeNIe version 4.0. To fit the data, use GeNIe's Tools|Metalog Builder window, or visit an on...

Re: Calculating values in Python and returning them to pySMILE
You can set node equation (as a string) with Network.set_node_equation. The actual formula depends on the type of the output from calculate_stress. To experiment with various node distributions using SMILE notation, you can use GeNIe's probability visualizer (available from the Tools menu), or go to...

Re: Issues with PC, questions to continuous networks, and more
Re: item 3, we will add an option to avoid zeros in the learned parameters. We already have similar functionality in the hybrid inference sampling algorithm. The replacement value for zero will be 1/N, where N is the numbers of records in the dataset.

Re: Issues with PC, questions to continuous networks, and more
Thanks for the long and detailed post. We will try to provide answers to all your questions in multiple posts. 1. We have added an entry in our issue tracker re: missing maxSearchTime for the PC learning. This is a simple change, and we should be able to implement it before the upcoming SMILE releas...
