WebTo apply the MDL principle to Bayesian networks we need to specify how we can perform the two encodings, the network itself (item 1) and the raw data given a network (item 2). 7 3.1 Encoding the Network To represent a particular Bayesian network, the following information is necessary and suf- cient: A list of the parents of each node. WebSince this is a Bayesian network polytree, inference is linear in n . Summary • Bayesian networks represent a joint distribution using a graph • The graph encodes a set of conditional independence assumptions • Answering queries (or …
