Mining Fuzzy Association Rules from Composite Items
A novel framework is described for mining fuzzy Association Rules (fuzzy ARs) relating the properties of composite attributes, i.e. attributes or items that each feature a number of values derived from a common schema. To apply fuzzy Association Rule Mining (ARM) we partition the property values into fuzzy property sets. This paper describes: (i) the process of deriving the fuzzy sets (Composit...
متن کاملMining Association Rules with Weighted Items
Discovery of association rules has been found useful in many applications. In previous work, all items in a basket database are treated uniformly. We generalize this to the case where items are given weights to re ect their importance to the user. The weights may correspond to special promotions on some products, or the pro tability of di erent items. We can mine the weighted association rules ...
متن کاملUse HypE to Hide Association Rules by Adding Items
During business collaboration, partners may benefit through sharing data. People may use data mining tools to discover useful relationships from shared data. However, some relationships are sensitive to the data owners and they hope to conceal them before sharing. In this paper, we address this problem in forms of association rule hiding. A hiding method based on evolutionary multi-objective op...
متن کاملManaging the Absence of Items in Fuzzy Association Mining
One of the most well-known and extended data mining techniques is that of association rule mining, a helpful tool to discover relations between items present in sets of transactions. Nevertheless, in some other scenarios, another interesting issue is that of considering not only the possible relations involving presence of items, but the absence of them. The problem gets more complex when it is...
متن کاملSensitive Items in Privacy Preserving - Association Rule Mining
The concept of Privacy-Preserving has recently been proposed in response to the concerns of preserving personal or sensible information derived from data mining algorithms. For example, through data mining, sensible information such as private information or patterns may be inferred from non-sensible information or unclassified data. As large repositories of data contain confidential rules that...
