Description: Apriori算法是发现关联规则领域的经典算法。该算法将发现关联规则的过程分为两个步骤：第一步通过迭代，检索出事务数据库中的所有频繁项集，即支持度不低于用户设定的阈值的项集；第二步利用频繁项集构造出满足用户最小信任度的规则-Apriori association rules algorithm is found in the field of classical algorithms. The algorithm will find the process of association rules is divided into two steps: first, through iteration, retrieve a transaction database of all the frequent itemsets, that is, support for no less than user-set threshold itemset the second step use of frequent itemsets constructed to meet the users trust in the rules of the smallest Platform: |

Description: Apriori is a seminal algorithm for fi nding frequent itemsets using candidate generation
[1]. It is characterized as a level-wise complete search algorithm using anti-monotonicity of
itemsets, “if an itemset is not frequent, any of its superset is never frequent”. By convention,
Apriori assumes that items within a transaction or itemset are sorted in lexicographic order.
Let the set of frequent itemsets of size k be Fk and their candidates be Ck . Apriori fi rst scans
the database and searches for frequent itemsets of size 1 by accumulating the count for each
item and collecting those that satisfy the minimum support requirement. It then iterates on
the following three steps and extracts all the frequent itemsets.-Apriori is a seminal algorithm for Platform: |
