Markov Blanket
	• Suppose we want to know the probability of each variable's values given all other variable values. • Recall P(x1, …, xn)  =      P(x1|ParentValues(x1)) * … *      P(xn|ParentValues(xn)) • In computing P(x1, …, xi, …, xn), which of the terms in the above product involve xi? • How would you describe the variables which appear in those terms? (see example) • These neighboring variables are called Xi's Markov blanket.
