4. Kernel functions can be defined over objects as diverse as graphs, sets, and text docu-ments. For instance consider the space of all possible subsets A of a given fixed set D. Show that the kernel function k(A1, A2) = 21AinA21 corresponds to an inner product in a feature space of dimensionality 21D1 defined by the mapping 0(A). Here A is a subset of D , Al n A2 denotes the intersection of sets Al and A2, and lAl denotes the number of elements in A. Find mapping 0(A) such that k(A1, A2) = XXXXXXXXXXA2)•
