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).

SMILE 2.2 Released

SMILE 2.2 is now available. This version of the library supports new diagnosis algorithms. The libraries for C++, Python, Java, R and .NET can be downloaded from https://download.bayesfusion.com . We also maintain repositories for use with Maven and pip, see the download website for more details. Su...

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

I use the Learn parametres function
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?

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...

Re: missing value

It seems the issue is with PC learning algorithm and the missing value replacement which is numeric. I ran PC with a data file with missing values replaced with the label "x99", and the output did contain the x99 outcome. When the missing value was replaced with a number (like 99), the out...

Re: missing value

The structure learning algorithms in SMILE/GeNIe currently require that a dataset has no missing values. From the POV of the learning algorithm the missing value replacement is no different from any state label. The PC algorithm should output the nodes with outcomes like S_99, just like the attached...

Re: how are the colors assigned to the nodes in a sensitivity analysis?

The values displayed in the tornado are actual target posterior changes for the specified parameter spread (see the slider control in the bottom part of the tornado dialog). These are not the derivatives. The coloring of the nodes when the sensitivity analysis is active is based on the derivatives. ...

Re: Error message when using continuous nodes

Your HOMA_IR node has finite bounds specified (0 to 20). The node equation was used 60000 times during discretization sampling. The equation inputs were uniformly selected from parent intervals (if there were any parents). Out of 60000 values sampled, only 20043 were within the bounds. 25758 samples...
