A Novel Apriori Algorithm Based on Cross Linker

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 216)


Based on the analysis of the Apriori algorithm from the perspectives of time complexity and memory complexity, a novel algorithm was proposed. The proposed algorithm defined a cross-linker structure firstly and then used this structure to substitute the array description of the transactions database. The cross linker structure shortened the length of the objects linked; thus, it reduced the algorithm’s time cost. The cross-linker structure did not save the candidates of frequent itemset also; thus, it reduced the algorithm’s memory cost. The experiments show that the proposed algorithm’s performances are comparable.
