Estimate the time complexity of Apriori algorithm.
Homework Answers
Suppose the number of input transactions is N, the threshold is M, number of unique elements is R. The complexity for generating set of size i is O(R^i) and the time for calculating support for each set can be done in O(n), if using HashMap. Therefore, time complexity would be O[(R + N) + (R^2 + N) + (R^3 + N) …] = O[MN + (R^1+R^2+ … R^M)] = O(MN+ (1-R^M)/(1-R))
