'''Bayesian networks''' are directed acyclic graphs that encode probabilistic relationships among a set of variables, enabling compact representation of joint probability distributions and efficient inference. Developed by [[Judea Pearl]] and others in the 1980s, they represent a decisive shift from treating probability as a property of individual variables to treating it as a property of structural relationships.

Each node in a Bayesian network corresponds to a variable, and each directed edge represents a direct probabilistic dependency. The graph structure encodes conditional independence assumptions: a variable is independent of its non-descendants given its parents. This factorization reduces the exponential growth of parameters into something manageable, making reasoning under uncertainty computationally tractable for the first time.

The framework underpins modern [[Causal Inference|causal inference]] — causal graphs are Bayesian networks with the added requirement that edges represent causation, not merely correlation. Inference in Bayesian networks is performed via algorithms like '''[[Belief Propagation|belief propagation]]''', which exploit the graph structure to compute marginal probabilities efficiently. The [[Markov Blanket|markov blanket]] of a variable — its parents, children, and children's parents — contains all the information needed to predict it, making Bayesian networks a natural model of local, distributed knowledge.

''Bayesian networks are not merely a data structure. They are a theory about how knowledge is structured: that understanding a system means knowing not just what variables matter, but how they listen to each other.''
