market basket analysis an unsupervised data mining technique for
determining sales patterns
Frequent Pattern Mining closed pattern X = no super-pattern Y given X with
the same support; max-pattern X = no super-
pattern Y given X
Apriori Algorithm A fast method of finding frequent itemsets, which
also involves pruning non-frequent items and self-
joining of k-itemsets only if their first (k-1) items are
the same.

(avoid candidate generation)
Association Rules Association rules specify a relation between
attributes that appears more frequently than
expected if the attributes were independent.
Correlation rules Measure of dependent/correlated events: lift(A,B) =
