Abstract

In fuzzy rough sets a fuzzy T-similarity relation is employed to describe the similarity degree between two objects and to construct lower and upper approximations for arbitrary fuzzy sets. Different triangular norm T identifies different point of view of similarity. Thus a reasonable selection of triangular norm is meaningful to practical applications of fuzzy rough sets.
