Your input datasets are transactional data with the following format: 25 52 164 240 274 328 368 448 538 561 630 687 730 775 825 834 39 120 124 205 401 581 704 814 825 834 35 249 674 712 733 759 854 950 39 422 449 704 825 857 895 937 954 964 15 229 262 283 294 352 381 708 738 766 853 883 966 978 26 104 143 320 569 620 798 7 185 214 350 529 658 682 782 809 849 883 947 970 979 227 390 71 192 208 272 279 280 300 333 496 529 530 597 618 674 675 720 855 914 932 Each line records a transaction (a set of items being purchased together). Your goal is to compute [login to view URL] co-occurrences of each pair of items, Count (A, B)=# of transactions contains both A and B, and the conditional probability Prob(B|A)=Count(A,B)/Count(A). [login to view URL] need implement both the “stripes” approach and the “pair” approach om Hadoop (See slides on MapReduce Algorithm Design and Chapter 3 in Jimmy Lin's textbook).
