WebMar 1, 2024 · In Bayesian Networks, one usually computes the kernels P ( V i ∣ P a ( V i)) where P a ( V i) are the parents of the node V i. In this case, you need to observe the variable V 3 jointly with its parents P a ( V 3) = { V 1, V 2 }. This is because in a DAG the local Markov condition allows for the factorization: Web• Bayesian networks represent a joint distribution using a graph • The graph encodes a set of conditional independence assumptions • Answering queries (or inference or reasoning) in …
