OpenMarkov

OpenMarkov is a handy program that allows you to evaluate and edit probabilistic graphical models, such as influence diagrams or Bayesian networks. The probabilistic graphical model or PGM for short refers to a probability distribution and consists of several variables and a graph. The graph includes nodes that represent each of the variable as well as some of the interdependencies of the distribution.

Perhaps one of the most known PGMs are the Bayesian networks and the influence diagrams. Highly popular for modeling complex and uncertain data, the Bayesian networks provide a robust and clear framework for analyzing issues related to ecosystems or the environment, for instance.

To support a mathematical framework, the app allows you to erase records whose values are missing. Then again, keep in mind that in some cases, the procedure may leave too few records in the database and the learning process unreliable.

The influence diagram is commonly employed to display the key elements that enable you to take an educated decision. However, the reliability of the findings and post-analysis in this situation is as good as the imposed policies you added. Since the role of the policies is to analyze the behavior in different scenarios and adding evidence, the app can return both optimal and non-optimal policies.
