A frequent itemset mining system, for instance, is characterized by the use of a minimum support constraint; an association rule mining system, similary, is identified by a minimum confidence constraint. Constraints define to a large degree which task a

Data Mining and Constraints: An Overview SpringerLink

网页2016年12月3日The use of constraints may be useful in the data mining process in at least three ways: (i) filtering and organizing the dataset before applying data mining methods; (ii) improving the performance of data mining algorithms by reducing the search space and focusing the search itself; and (iii) reasoning on the results of the mining step

Itemset mining: A constraint programming perspective

网页2011年8月1日Indeed, in our formulation of scriminative itemset mining, we introduce a novel primitive by means of a global constraint. This is common practice in nstraint programming, and the identification and study of global constraints that can effectively solve specific subproblems s become a branch of research on its own [6].

Mining sequential rules with itemset constraints SpringerLink

网页2021年3月1日Mining sequential rules from a sequence database usually returns a set of rules with great cardinality. However, in real world applications, the end-users are often interested in a subset of sequential rules. Particularly, they may consider only rules that contain a specific set of items. The naïve strategy is to apply such itemset constraints

Mining constraint relationships and redundancies with

网页In optimization, constraints are often defined to eliminate solutions which are not physically feasible or practical. Unfortunately, in some cases, designers may unknowingly or inadvertently specify constraints which are redundant. Common causes and consequences of superfluous con- straints have been discussed by Karwanet al.(1983).
