WebJul 15, 2024 · Probabilistic graphical model (PGM) provides a graphical representation to understand the complex relationship between a set of random variables (RVs). RVs represent the nodes and the statistical dependency between them is called an edge. An example of how a probabilistic graphical model looks like is shown above. Similar to Bayesian networks, MRFs are used to describe dependencies between random variables using a graph. However, MRFs use undirected instead of directed edges. They may also contain cycles, unlike Bayesian Networks. Thus, MRFs can describe a different set of dependency relationships than their … See more As the name already suggests, directed graphical models can be represented by a graph with its vertices serving as random variables and directed edges serving as dependency relationships between them (see figure below). … See more How are Bayesian Networks and Markov Random Fields related? Couldn’t we just use one or the other to represent probability distributions? How can we establish equivalence? One may try to convert a BN to a MRF … See more Probabilistic Graphical Models present a way to model relationships between random variables. Recently, they’ve fallen out of favor a little bit due to the ubiquity of neural networks. However, I think that they will still be … See more ryerson french minor
