The existing fuzzy rough set (FRS) models all believe that the decision attribute divides sample into several “clear” classes, and this data processing method makes model sensitive to noise information when conducting feature selection. To solve problem, paper proposes a robust (RS-FRS) based on representative samples. Firstly, membership degree of samples is defined reflect its fuzziness uncer...

Aiming at solving the uncertainty of knowledge in variable precision fuzzy soft rough set model. Firstly, from perspectives approximated and equivalent approximation space, measurement methods model are defined, such as information granularity, entropy, etc; Secondly, many related theorems given proved, monotonicity obtained when relation satisfies inclusion condition; Finally, feasibility vali...
