I want to use the Probabilistic graphical model toolkit for my research. (preferably MATLAB based).

There seems to be pretty a lot of different toolkits available online (UGM, Bayes Net Toolbox for Matlab, PMTK:probabilistic modeling toolkit for Matlab/Octave,Mens X Machina Probabilistic Graphical Model Toolbox (PGM Toolbox)).

Could you recommend 1) the most popular and widely used toolkit for PGMs and 2) the easiest toolkit with demos that I can gain some hands-on exposure?


  • $\begingroup$ BNT has good demos and is easy to use. PMTK is developed by the same person so it probably has considerable overlap. $\endgroup$

I am also having same question of yours for my upcoming research usage. You may find the following link useful where all existing tools are summarized:


I am personally planning to use the PMTK tool.

Hope it may help.
