WebAug 30, 2024 · Probabilistic graphical models (PGMs) are a rich framework for encoding probability distributions over complex domains: joint (multivariate) distributions over large numbers of random variables that interact with each other. These representations sit at the intersection of statistics and computer science, relying on concepts from probability ... WebGraphical models are often used to model multivariate data, since they allow us to represent high-dimensional distributions compactly; they do so by exploiting the interdependencies that typically exist in such data. Put simply, we can take advantage of the fact that high-dimensional distributions can often be decomposed into low-dimensional …
