Sažetak	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.	Three-Way Decisions (3WD) is a decision-theoretic framework, introduced by Yiyu Yao in 2010, that partitions the universe of objects into three regions—positive (accept), negative (reject), and boundary (abstain)—using probabilistic rough set theory. Unlike binary classifiers that force every object into one of two classes, 3WD explicitly acknowledges uncertainty by allowing a third option: deferring judgment when available evidence is insufficient for a confident decision.
