problem 1: A database has five transactions. Let min sup = 60% and min con f = 80%.

T200               {D, O, N, K, E, Y}
T300               {M, A, K, E}
T400               {M, U, C, K, Y}
T500               {C, O, O, K, I, E}

a) Find out all frequent item sets using Apriori and FP-growth, correspondingly. Compare the efficiency of the two mining processes.

b) List out all of the strong association rules (with support s and confidence c) matching the following meta rule, where X is a variable representing customers, and itemi denotes variables representing items (e.g., “A”, “B”, etc.): Vx belongs transaction, buys(X, item1)^buys(X, item2))buys(X, item3) [s, c]

problem 2: prepare algorithm for FP-growth.

problem 3: Describe Apriori Algorithm with illustration.

problem 4: Describe how to mine multi-dimensional association rules from Relational data bases.
