Uncertainty Measures of Rough Set Prediction
The main statistics used in rough set data analysis, the approximation quality, is of limited value when there is a choice of competing models for predicting a decision variable. In keeping within the rough set philosophy of non–invasive data analysis, we present three model selection criteria, using information theoretic entropy in the spirit of the minimum description length principle. Our ma...
متن کاملVagueness and Uncertainty: A Rough Set Perspective
Vagueness and uncertainty have attracted attention of philosophers and logicians for many years. Recently AI researchers contributed essentially to this area of research. Fuzzy set theory and the theory of evidence are seemingly the most appealing ones. In this note we present a new outlook on these problems, based on the rough set theory-which seems to be a very suitable mathematical tool to d...
متن کاملApproximation of Classification and Measures of Uncertainty in Rough Set on Two Universal Sets
The notion of rough set captures indiscernibility of elements in a set. But, in many real life situations, an information system establishes the relation between different universes. This gave the extension of rough set on single universal set to rough set on two universal sets. In this paper, we introduce approximation of classifications and measures of uncertainty basing upon rough set on two...
متن کاملUncertainty measures in multigranulation with different grades rough set based on dominance relation
The graded rough set and multi-granulation rough set are two significant generalized rough set models which be constructed on the indiscernibility relation. They solve the issues that the degree of overlap between the equivalence class and basic set in different view points of quantitative information. The purpose of this study is that research the good points of graded rough set in the multi-g...
متن کاملInformation Entropy and Mutual Information-based Uncertainty Measures in Rough Set Theory
As an extension of the classical set theory, rough set theory plays a crucial role in uncertainty measurement. In this paper, concepts of information entropy and mutual information-based uncertainty measures are presented in both complete and incomplete information/decision systems. Then, some important properties of these measures are investigated, relationships among them are established, and...
