Data mining is the process of extracting useful information from the huge amount of data stored in the databases. Data mining tools and techniques help to predict business trends those can occur in near future. Association rule mining is an important technique to discover hidden relationships among...
Section 5: The extensions of association mining needed for intuitionistic fuzzy sets are described, in particular the required set cardinality used for association rule generation. The running example extended to fuzzy intuitionistic data is then used to illustrate the approach using the various metrics...
三、FP-tree 四、挖掘多层关联规则 1.uniform support: 层间支持度相同,若祖先不频繁,则其后代也不频繁,可剪枝。 2.reduced support: 层间支持度递减,若祖先不满足本层最小支持度,其后代可能满足,若剪枝会丢失频繁项。
In addition, this framework allows ad-hoc data mining queries over the whole data warehouse, not just over a transformed portion of the data that is required when a standard data-mining tool is used. Finally, this framework also expands the domain of association-rule mining from transaction-...

Data Mining of Association Rules and the Process of Knowledge Discovery in Databases Summary: In this paper we deal with association rule mining in the context of a complex, interactive and iterative knowledge discovery process. After a general introduction covering the basics of association rule mini...
database, people further hold the necessary to maintain any knowledge so while not to be worked out, like delicate common itemsets, practices, taxonomy tree and the like Association rule mining can make a possible warning approaching the secrecy of information. So, association rule hiding methods ...

We have used an Association Rule based data mining approach to dynamically identify rule changes and quickly update the rule set to maintain optimal performance consistently on two real-time problem areas namely Web Cache Maintenance and Intrusion Detection. In the first problem, a multi-agent ...
