Mining negative association rules
The focus of this paper is the discovery of negative association rules. Such association rules are complementary to the sorts of association rules most often encountered in literatures and have the forms of X→¬Y or ¬X→Y. We present a rule discovery algorithm that finds a useful subset of valid negative rules. In generating negative rules, we employ a hierarchical graph-structured taxonomy of do...
متن کاملMining Positive and Negative Fuzzy Association Rules
While traditional algorithms concern positive associations between binary or quantitative attributes of databases, this paper focuses on mining both positive and negative fuzzy association rules. We show how, by a deliberate choice of fuzzy logic connectives, significantly increased expressivity is available at little extra cost. In particular, rule quality measures for negative rules can be co...
متن کاملException Rules Mining Based on Negative Association Rules
Exception rules have been previously defined as rules with low interest and high confidence. In this paper a new approach to mine exception rules will be proposed and evaluated. Interconnection between exception and negative association rules will be considered. Based on the knowledge about negative association rules in the database, the candidate exception rules will be generated. A novel exce...
متن کاملHierarchical decision rules mining
Decision rules mining is an important technique in machine learning and data mining. It has been studied intensively during the past few years. However, most existing algorithms are based on flat dataset, from which a set of decision rules mined may be very large for large scale data. Such a set of rules is not easily understandable and really useful for users. Moreover, too many rules may lead...
متن کاملEfficient Algorithm for Hierarchical Online Mining of Association Rules
-------------------------------------------------------------------------ABSTRACT---------------------------------------------------------------Several multi-pass algorithms have been proposed for Association Rule Mining from static repositories. However, such algorithms are incapable of online processing of transaction streams. In this paper we introduce an efficient single-pass algorithm for ...
