Assocaition Rule Mining with Itemwise Support Thresholds

ثبت نشده
چکیده

Most of the association rule mining algorithm works based on the assumption that the items present in the dataset are of same kind with similar frequencies. Hence, the algorithms use levelwise support thresholds for mining. When the itemsets are of different frequency and of varied importance, the levelwise support thresholds are not suitable to discover frequent associations. Each item in a level reflects different characteristics and regularities. To produce low support and high confidence association rules, it is necessary to specify support thresholds for each item.

CMRules: Mining Sequential Rules

Sequential rule mining is an important data mining task with wide applications. However, current algorithms for discovering sequential rules common to several sequences use very restrictive definitions of sequential rules, which make them unable to recognize that similar rules can describe a same phenomenon. This can have many undesirable effects such as (1) similar rules that are rated differe...
