Semantics The full joint distribution is defined as the product of the local conditional distributions: n P(X1,..,Xn)=TTi=1P (Xil Parents(X)) e.g.,P(inmnan-bn-e) =P(jl a)P(m l a)P (al-b,-e)P(-b)P(-e)Semantics The full joint distribution is defined as the product of the local conditional distributions: P (X1 , … ,Xn ) = πi = 1 P (Xi | Parents(Xi )) e.g., P(j  m  a  b  e) = P (j | a) P (m | a) P (a | b, e) P (b) P (e) n
