Incrementally updating approximations based on the graded tolerance relation in incomplete information tables

Object-First Incremental Algorithms for Updating Approximations in Multi-Granulation Fuzzy Probabilistic Rough Sets Over Two Universes

“…However, the data always change over time in reality. In this regard, some scholars have done a lot of researches mainly from three viewpoints: attribute change [26]- [28], attribute value change [29]- [31], and object change [32]- [34]. In the information system over two universes, Hu et al [35] proposed a kind of incremental algorithm of fuzzy probabilistic rough sets.…”
