Our papers

If you are new to function decomposition, start with the paper that appeared in IEEE Intelligent Systems and their Applications [2]. It describes the basic decomposition algorithm that deals with multi-valued attributes and class, and discovers classifiers that are 100% consistent with original data sets. We named this algorithm as minimal-complexity decomposition, as the method thrives to decomposition the original data set to a set of smaller data sets. An extended version of this paper appeared in the book by H. Liu and H. Motoda [3].

Minimal-complexity decomposition is in the detail described in the paper that appeared in Artificial Intelligence Journal [5]. The shorter version of this paper was presented in ICML-97 [4]. Different partition selection methods are investigated in the paper published in Informatica [11].

A paper at KDD-97 [6] presents how function decomposition can be viewed within a data mining framework. It is in this paper that we first introduce the so-called "supervised" function decomposition, that is, a function decomposition that is to guided by the human expert in selecting the concepts that are worth constructing. The idea was pushed further by allowing the expert to, if needed, change or suggest some parts of the functions that are discovered by decomposition [10], but further investigations (and a program with a nice user interface) is needed. How function decomposition may be considered as a tool to automatically construct a decision support models was presented at ISDSS-1997 [7].

Noise handling in function decomposition is one of the main contributions of the PhD Thesis by B. Zupan [1]. This part of the Thesis was subsequently presented at ICML-2000 [8].

Function decomposition and its application in handling continuous data was only marginally studied. One of the few attempts to deal with this problem was presented at ECML-97 [9].
