“Forward sampling” can also be performed efficiently on undirected models if the model can be represented by a clique tree with a small number of variables per node. Calibrate the clique tree, which gives us the marginal distribution over each node, and choose a node to be the root. See more As a warm-up, let’s think for a minute how we might sample from a multinomial distribution with k possible outcomes and associated probabilities θ1,…,θk. Sampling, in general, is not an easy problem. Our … See more Sampling from a distribution lets us perform many useful tasks, including marginal and MAP inference, as well as computing integrals of the form If f(x) does not have special … See more Let us now turn our attention from computing expectations to performing marginal and MAP inference using sampling. We will solve these problems using a very powerful technique called Markov chain Monte … See more Web4.
