Question

A database has five transactions. Let min sup = 60% and min con f = 80%. (a) find all frequent itemsets using apriori. (b) list all of the strong association rules

Answer 1

Answer:

ASSOCIATION RULE:

[E,K] → 0 = 3/4 = 75%

[K,O] → E = 3/3 = 100%

[E,O] → K = 3/3 = 100%

E → [K,O] = 3/4 = 75%

K → [E,O] = 3/5 = 60%

O $\rightarrow$ [E,K] = 3/3 = 100%

$\therefore$ Rule no. 5 is discarded because confidence $\ge$70%

So, Rule 1,2,3,4,6 are selected
