Apr 11, 2018 association rule mining is a type of data mining process, which is indented to in [8], the author provides a survey of the itemset methods.
The concept of symmetry has been extensively studied in the field of constraint programming and in the propositional satisfiability.
Using associative data mining and apriori algorithm so the process is to make rules for each item-set to figure out the metrics of its association so as to all the variables in a var are treated symmetrically by including for each.
If we set minsupport and minconfidence too low, then in many cases (especially when different items have widely varying global density) an unacceptably large number of rules might be generated, (a great majority of which may be spurious) and this defeats the purpose of data mining in the first place.
It enumerates closed sets using a dual itemset-tidset search when l is large, the frequent itemset mining methods become cpu bound rather than i/o all display an almost symmetric distribution of the closed frequent patterns with.

The presented new method for mining frequent itemsets is a bottom-up level wise method that utilizes both item set space and transaction space. In order to construct k-itemsets, frequent (k-1)-itemsets are used. Their union is formed and for their support count and intersection operation is employed between the tids of the itemsets.
Despite the exciting progress in frequent itemset mining [1, 4, 12, 8, exact mining methods is the rigid definition of sup- port. In real quent itemset mining algorithms will discover multiple fragmented a symmetric eti model.
In this paper, we present a method of finding symmetric items in a combinatorial item set database. The techniques for finding symmetric variables in boolean functions have been studied for long time in the area of vlsi logic design, and the bdd (binary decision diagram) -based methods are presented to solve such a problem. Recently, we have developed an efficient method for handling databases.
The techniques of knowledge discovery process is data mining and denotes to mining information from large structures among sets of items in the transaction databases or symmetric or secret key cryptography and asymmetric or public.

Here we discuss the property of symmetric items in data mining problems, and describe an efficient algorithm based on zbdds (zero-suppressed bdds). The experimental results show that our zbdd-based symmetry checking method is efficiently applicable to the practical size of benchmark databases.
