Description: Apriori core algorithm process is as follows:
After single trip brain-scan database D calculated each 1 itemsets support and get frequent 1 itemsets collection.
Connect step: in order to create, a predetermined by 2 generate, only one item different belongs to the frequency of the set a (k- 2) JOIN operation get.
The pruning step: because yes superset and may, therefore, some elements are not frequent. In potential k itemsets is a subset of the members of the potential is, the frequent itemsets impossible is the frequent can find removed.
Through a single trip brain-scan database D, calculation of various itemsets support and will not satisfy the support degree itemsets removed form.
