چکیده

During years, many new types of association rules have been found and well studied ([11], [10], [2], [4]). This work defines new type of association rules based on generalization of definitions of some existing rule types. We also study here its theoretical features; namely e.g. non-symmetricity, monoty, quasi-transitivity. Moreover, the paper provides a method for visualizing such rules using Hasse diagrams and concept lattices.

Characteristics of cosymmetric association rules

Association rules are essential data mining tool and as such has been well researched. Many new types of association rules based on both categorial or quantitative data have been founded ([8], [7], [2], [4]). Our work is directed to the theoretical features of association rules; especially, we study a specific class of association rules called δ-cosymmetric rules. We present here some interesti...

Experimental Investigation of Asymmetry of Vortex Flow Over Single Delta Wings

It is generally believed that, on slender delta wings, there is a critical state at which strong asymmetric vortices are found along the leading edge on the lee-side of the delta wing. These asymmetric vortices can lead to high lateral forces even when slender delta wing is at the zero angle of yaw. Some experimental studies reported recently, cast considerable doubt as to the validity of the a...

A KDDSE-independent PMML Visualizer

Several knowledge discovery support engines (KDDSE) feature the export and in a few cases even the import of data mining models in the Predictive Modeling Markup Language (PMML) standard. A visualization tool for PMML models that is independent of a specific KDDSE is presented in this paper. An extension of the PMML model for association rules that allows the definition of propositional and fir...

Association Rules in the Relational Calculus

One of the most utilized data mining tasks is the search for association rules. Association rules represent significant relationships between items in transactions. We extend the concept of association rule to represent a much broader class of associations, which we refer to as entity-relationship rules. Semantically, entity-relationship rules express associations between properties of related ...

Visualization to assist users in association rule mining tasks

Since the definition of the association rule mining problem in Agrawal’s 1993 paper, several efficient algorithms have been introduced to tackle the problem. Nevertheless, most of the approaches focuses on increasing algorithm efficiency, neglecting the fact that association rule mining poses many practical difficulties to users. Mining useful information is not straightforward, and neither is ...
