| 摘要≠ | Variable Precision Rough Set (VPRS) is an extension of classical rough set theory introduced by Wojciech Ziarko in 1993 to handle real-world data that inevitably contains noise and misclassification. By introducing a precision parameter u controlling the allowable degree of overlap between equivalence classes and a target concept, VPRS relaxes the strict subset requirement of standard rough sets, enabling the induction of approximate classification rules from noisy or inconsistent datasets. | Granular computing is a problem-solving paradigm that processes information in 'granules' — clumps of objects drawn together by indistinguishability, similarity, or functionality — rather than at the level of individual data points. Articulated by Lotfi Zadeh in 1997 as fuzzy information granulation and developed into a broad framework, it provides a unifying umbrella over fuzzy sets, rough sets, and interval methods, letting analysis move to whichever level of detail a problem actually requires. |
