• W2420188602 abstract "Association rule analysis is the task of discovering association rules that occur frequently in a given transaction data set. Its task is to find certain relationships among a set of data (itemset) in the database. It has two measurements: Support and confidence values. Confidence value is a measure of rule’s strength, while support value corresponds to statistical significance. Traditional association rule mining techniques employ predefined support and confidence values. However, specifying minimum support value of the mined rules in advance often leads to either too many or too few rules, which negatively impacts the performance of the overall system. In this paper, it is proposed to replace the Apriori’s user-defined minimum support threshold with a more meaningful aggregate function based on Central Limit Theorem (CLT). The paper also proposes a new function, MinAbsSup with bit mapping, which calculates a custom minimum support for each item set based on the probability of collision chance of its items. Furthermore, a modification for Apriori algorithm to accommodate this function is proposed. Experiments on large set of data bases have been conducted to validate the proposed framework. The achieved results show that there is a remarkable improvement in the overall performance of the system in terms of run time, the number of generated rules," @default.
