Evolutionary algorithms and fuzzy sets for discovering temporal rules

A novel method is presented for mining fuzzy association rules that have a temporal pattern. Our proposed method contributes towards discovering temporal patterns that could otherwise be lost from defining the membership functions before the mining process. The novelty of this research lies in exploring the composition of fuzzy and temporal association rules, and using a multi-objective evoluti...

Fuzzy Sets-based Control Rules for Terminating Algorithms

In this paper some problems arising in the interface between two different areas, Decision Support Systems and Fuzzy Sets and Systems, are considered. The Model-Base Management System of a Decision Support System which involves some fuzziness is considered, and in that context the questions on the management of the fuzziness in some optimisation models, and then of using fuzzy rules for termina...

Crossing unordered sets of rules in evolutionary fuzzy controllers

In recent years the use of Genetic or Evolutionary techniques has produced interesting results on the automatic generation of Knowledge Bases for Fuzzy Logic Controllers. Three diierent representations of the rule base have been considered: list of rules, relational matrix and decision table. The use of lists of rules reduces the dimension of the rule base but presents some handicaps for crosso...

Efficient Algorithms for Discovering Association Rules

Association rules are statements of the form "for 90 % of the rows of the relation, if the row has value 1 in the columns in set W, then it has 1 also in column B". Agrawal, Imielinski, and Swami ntroduced the problem of mining association rules from large collections of data, and gave a method based on successive passes over the database. We give an improved algorithm for the problem. The meth...

Learning Fuzzy Rules with Evolutionary Algorithms - An Analytic Approach

This paper provides an analytical approach to fuzzy rule base optimization. While most research in the area has been done experimentally, our theoretical considerations give new insights to the task. Using the symmetry that is inherent in our formulation, we show that the problem of finding an optimal rule base can be reduced to solving a set of quadratic equations that generically have a one d...
