Consider we have a very small item catalog with 3 items, and have gathered co-occurence counts in the following matrix. Note that the co-occurence matrix is symmetric as mentioned in class. We show the counts Cii to represent the number of times users bought item i by itself (without any other purchases. Computer the Jaccard similarity between items A and C using this co-occurrence matrix. Be careful that you don't overcount the number of times someone bought A and C together! Enter your answer as a decimal number rounded to two digits. A B C A 20 12 6 B 12 7 5 C 6 5 3
