Question: 8.25 ( ) In (8.86), we verified that the sum-product algorithm run on the graph in Figure 8.51 with node x3 designated as the root
8.25 ( ) In (8.86), we verified that the sum-product algorithm run on the graph in Figure 8.51 with node x3 designated as the root node gives the correct marginal for x2. Show that the correct marginals are obtained also for x1 and x3. Similarly, show that the use of the result (8.72) after running the sum-product algorithm on this graph gives the correct joint distribution for x1, x2.
