In this paper, we propose two methods that benefit from some novel fuzzy rough set models. Some theoretical preliminaries pave the way. First, by means of a fuzzy logical implicator Iand a triangular ...

The main goal of this manuscript is to introduce a discrete dynamical system defined by symmetric ... Note that the eigenvalue set σ(A) of A exists, but its elements are unknown explicitly in the ...

Abstract: In this article, a novel fuzzy α-neighborhood operator with reflexivity is constructed and a new fuzzy rough set model based on the fuzzy α-neighborhood operator is proposed. Aiming at ...

In a world super-charged by technology and with science and math jobs more in-demand than ever, how do we help students gain access in high school to the highest levels of math that will set them ...
