class pgmpy.base.UndirectedGraph (ebunch=None) [source] ¶. Base class for all the Undirected Graphical models. UndirectedGraph assumes that all the nodes in graph are either random variables, factors or cliques of random variables and edges in the graphs are interactions between these random variables, factors or clusters. Bayesian models that have been used in these contexts have many different forms. The differences between these models derive from distinct assumptions about the variables in the world and the way they relate to one another. Each model is then the unique consequence of one set of assumptions about the world.

Bayesian statistics is a theory in the field of statistics based on the Bayesian interpretation of probability where probability expresses a degree of belief in an event.The degree of belief may be based on prior knowledge about the event, such as the results of previous experiments, or on personal beliefs about the event. Bayesian model NlpTools, for now at least, only implements the Naive Bayes model. The interface of the model is the following. $ conda create -n pgmpy-env python=3.4 $ source activate pgmpy-env Once you have the virtual environment setup, install the depenedencies using: $ conda install -f requirements.txt # use requirements-dev.txt if you want to run tests Note: In order to build the documentation you will need sphinxand to run the tests you will need nose 3 May 28, 2018 · This article serves the purpose of collecting useful materials for learning probabilistic graphical models.

By now, pgmpy supports most of the fundamental operations on probabilistic graphical models (PGMs). Given a data set and a suitable Bayesian network model, pgmpy can parametrize the model based on the data and perform the usual array of inference and sampling tasks. But the model itself must still be supplied manually.
