We have just released the first versions of our toolboxes for MATLAB®:
Mens X Machina Bayesian Network Toolbox aims to provide a comprehensive set of tools for bayesian network inference and structure learning. Currently only bayesian network skeleton learning using the MMPC algorithm is implemented. Support for full structure learning and inference will be added in future versions.
Mens X Machina Commons Toolbox is a MATLAB toolbox with common functions (to be) used in other toolboxes provided by Mens X Machina, including the Bayesian Network Toolbox.
