"Rough group undetermined information analysis (RNIA) and its application"
We are conducting research to generate dependencies in tabular data as rules, and we propose and implement NIS-app-orithm to further expand the generative function to incomplete information. The rules obtained by RNIA are used for decision-making support, complementing missing values, extracting and selecting characteristics, and understanding of attribute dependencies. Since table data can be processed uniformly, it is highly versatile, and because it processes discrete value table data, which is difficult to define average and dispersion, it will also lead to complementing statistical methods.
