1 function marginal = marginal_nodes(engine, nodes, t, add_ev) | |
2 % MARGINAL_NODES Compute the marginal on the specified query nodes (loopy_unrolled_dbn) | |
3 % marginal = marginal_nodes(engine, nodes, t) | |
4 % | |
5 % 't' specifies the time slice of the earliest node in 'nodes'. | |
6 % 'nodes' must occur in some clique. | |
7 % | |
8 % Example: | |
9 % Consider a DBN with 2 nodes per slice. | |
10 % Then t=2, nodes=[1 3] refers to node 1 in slice 2 and node 1 in slice 3, | |
11 % i.e., nodes 3 and 5 in the unrolled network, | |
