7. Assume that we have a Bayes' Net of four variables A, B, C, D, and we currently have the following three factors: C fr(B,C) А ta ta С +c B +b -b +b -b +c fi(A, B) 0.1 0.4 0.2 0.5 B +b +b -b -b -C 0.2 0.1 0.5 0.1 +c D f2(C, D) td 0.2 -d 0.1 td 0.5 -d 0.1 -a .+c -C -a -C - Assume we are running Variable Elimination (VE), and the next step is to eliminate C. (a) Which factors will participate in the elimination process of C? (b) Perform the join over the factors that participate in the elimination of C. Your answer should be a table similar to the tables above. You have to figure out what should be the size of the table and what the numerical entries are. (c) Perform the summation over C for the factor you obtained from the join. Your answer should a table similar to the tables above. You have to figure out what should be the size of the table and what the numerical entries are.
