چکیده

We propose a novel framework and an algorithm for mining gradual dependencies between attributes in a data set. Our approach is based on the use of fuzzy rank correlation for measuring the strength of a dependency. It can be seen as a unification of previous approaches to evaluating gradual dependencies and captures both, qualitative and quantitative measures of association as special cases.

Measuring Variation Strength in Gradual Dependencies

In this paper we extend a previous definition of gradual dependence as a special kind of (crisp) association rule, in order to measure not only the existence of a tendency, but its strength. The new proposal is based on the idea of fuzzy association rule and the definition of variation strength in the degree of fulfilment of an imprecise property by different objects. We study the new semantics...

Fuzzy Rules in Data Mining: From Fuzzy Associations to Gradual Dependencies

Fuzzy rules, doubtlessly one of the most powerful tools of fuzzy logic, have not only been used successfully in established application areas like control engineering and approximate reasoning, but more recently also in the field of data mining. In this chapter, we provide a synthesis of different approaches to fuzzy association analysis, that is, the data-driven extraction of interesting patte...

Fuzzy Extended Dependencies to Support Decision-Making in Project Management

Project management is becoming an important key process in industrial engineering in order to choose suitable and profitable projects for the companies. We have focused our interest from the manager point of view that needs quality data to make decisions about which kind of projects are more suitable for the company. But nowadays the suitability of the projects don’t depend only on quantitative...

Multi-Core Parallel Gradual Pattern Mining Based on Multi-Precision Fuzzy Orderings

Gradual patterns aim at describing co-variations of data such as the higher the size, the higher the weight. In recent years, such patterns have been studied more and more from the data mining point of view. The extraction of such patterns relies on efficient and smart orderings that can be built among data, for instance, when ordering the data with respect to the size, then the data are also o...

Comparison of Linguistic Summaries and Fuzzy Functional Dependencies Related to Data Mining

Data mining methods based on fuzzy logic have been developed recently and have become an increasingly important research area. In this chapter, the authors examine possibilities for discovering potentially useful knowledge from relational database by integrating fuzzy functional dependencies and linguistic summaries. Both methods use fuzzy logic tools for data analysis, acquiring, and represent...
