= Junction tree algorithm
{wiki=Junction_tree_algorithm}
The Junction Tree Algorithm is a method used in probabilistic graphical models, notably in Bayesian networks and Markov networks, to perform exact inference. The algorithm is designed to compute the marginal probabilities of a subset of variables given some evidence. It operates by transforming a graphical model into a junction tree, which is a specific type of data structure that facilitates efficient computation. \#\#\# Key Concepts 1. **Graphical Models**: These are representations of the structure of probability distributions over a set of random variables.
