Hierarchical decision models are a general decision support methodology aimed at the classification or evaluation of options that occur in decision-making processes. They are also important for the analysis, simulation and explanation of options. Decision models are typically developed through the decomposition of complex decision problems into smaller and(More)
A decision making approach which combines multi-attribute decision making techniques with expert systems is described in the paper. In this approach, knowledge about a particular decision making problem is represented in the form of tree-structured criteria and decision rules. Decision making is supported by an expert system shell. In the paper, the(More)
This paper attempts to describe and clarify the meaning of the term Decision Support (DS). Based on a survey of DSrelated WWW documents, and taking a broad view of DS, a classification of DS and related disciplines is presented. DS is put in the context of Decision Making, and some most important disciplines of DS are overviewed: Operations Research,(More)
While not explicitly intended for feature transformation, some methods for switching circuit design implicitly deal with this problem. Given a tabulated Boolean function, these methods construct a circuit that implements that function. In 1950s and 1960s, Ashenhurst [1] and Curtis [2] proposed a function decomposition method that develops a switching(More)
We present a novel data mining approach based on decomposition. In order to analyze a given dataset, the method decomposes it to a hierarclay of smaller and less complex datasets that can be analyzed independently. The method is experimentally evaluated on a real-world housing loans allocation dataset, showing that the decomposition can (1) discover(More)
We propose architecture of an active life-event portal, which draws on knowledge-based concepts and methods. The portal consists of three main modules: logical, data and control. They operate on three levels: topics, lifeevents and services. We present the functionality and operation of the modules, and propose knowledge representation methods for each(More)
We present a new machine learning method that, given a set of training examples, induces a definition of the target concept in terms of a hierarchy of intermediate concepts and their definitions. This effectively decomposes the problem into smaller, less complex problems. The method is inspired by the Boolean function decomposition approach to the design of(More)
