Outline of Final Research Achievements

Rough set theory is a mathematical framework for mining table data sets. This theory is utilized for generating the characteristic implications (rules), and is applied to the recognition of the properties and decision support in table data sets. Principal investigator introduced the modal logic (possible worlds semantics) in rough set theory, and proposed Rough set Non-deterministic Information Analysis (RNIA) that can be taken into account to non-deterministic information. Because, the computational complexity problem was solved, RNIA became a quite unique framework. The proposed NIS-Apriori algorithm is employed as the core algorithm, and related problems like minor rule mining, the improvement of the analytic software tool, the improvement toward big data analysis, the analysis of the actual data sets, privacy-preserving data mining, the estimation of missing values, were solved by the NIS-Apriori algorithm.
