Apriori Algorithm – Lecture Notes

Example: \(F_3 = \{ (1~ 2~ 3), (1~ 2~ 4), (1~ 3~ 4), (1~ 3~ 5), (2~ 3~ 4)\}\) After join: \(\{ (1~ 2~ 3~ 4), (1~ 3~ 4~ 5)\}\) pruning step: remove \((1~ 3~ 4~ 5)\) because \((3~ 4~ 5), (1~ 4~ 5) \not\in F_3\) [...] apriori-gen Step 1: Join by prefix matching Process all \((k-1)\) -frequent itemsets \(p\lt{}q\) , that match on their first \(k-2\) elements \(p \in F_{k-1}:\) ( 1 2  3) \(\downarrow\) ( 1 2  3 4) \(\in [...] \(\in C_k\) \(\uparrow\) \(q \in F_{k-1}:\) ( 1 2  4) Step 2: Pruning Remove all candidate itemsets that have a subset of size \((k-1)\) that is not in \(F_{k-1}\) Note: faster on sorted itemsets.

intuition. Let A1 := {0, 1, 0, 1, · · · , 0, 1}, with alternating values. We have C(A1|M (1) 1 ) = 16H(1/2) = 16 and C(M (1) 1 ) = log!16 + #log(16 + 1)$ = 10 + 5 = 15.
