A Note on Ziarko’s Variable Precision Rough Set Model and Nonmonotonic ReasoningGranular reasoning is a way of reasoning using granularized possible worlds and lower approximation in rough set theory. However, it can deal only with monotonicity. Then, the extended lower approximation in Ziarko’s variable precision rough set model is introduced to describe nonmonotonic reasoning.

Decision Networkss. Every path in the graph represents a chain of decision rules, which describe compound decision..Some properties of decision networks will be given and a simple example will illustrate the presented ideas and show possible applications.

A Comparative Study of Formal Concept Analysis and Rough Set Theory in Data Analysisnstructed. Formal concept analysis focuses on concepts that are definable by conjuctions of properties, rough set theory focuses on concepts that are definable by disjunctions of properties. They produce different types of rules summarizing knowledge embedded in data.
