Rough Set Theory is a mathematical framework devised to manage uncertainty in data by utilising lower and upper approximations to characterise vague or imprecise information. The theory, originally ...

Set theory is a mathematical abstract concerned with the grouping of sets of numbers that have commonality. For example, all even numbers make up a set, and all odd numbers comprise a set. All numbers ...

Rough set theory has emerged as a robust mathematical framework for managing uncertainty and imprecision within information systems. By utilising the principles of lower and upper approximations, this ...
