A decision graph is a generalization of a decision tree that allows nodes (i.e., attributes used for splits) to have multiple parents, rather than just a single parent. The resulting graph must still be acyclic. Now, consider the XOR function of three binary input attributes, which produces the value 1 if and only if an odd number of the three attributes has value 1. 1. Draw a minimal-sized decision tree for the three-input XOR function. 2. Draw a minimal-sized decision graph for the three-input XOR function. 0 1 0, 1 01 1 0 0 0 1 0 0 0 11 1 0 0
