Associative classifier algorithms combine two data mining paradigms, namely sample classification andassociation rule mining. These methods are very interesting for building an accurate classification model in a wide area of real-world applications. Lately, many methods have been presented to integrate associative classifiers with fuzzy set theory, in order to improve the quality of previous algorithms. This paper presents a three-step fuzzy frequent pattern (FFP) based classifier which uses an Apriori like algorithm to generate a large number of FFPs from each data class. Our algorithm in the second stepselects a subset of useful FFPs and removes redundant ones. Finally, in order to tune the boundaries between various data classes, we use a confidence improvement process. We tested our algorithm on six real-world datasets and compared the achieved results with two well-known fuzzy associative classifier algorithms.
