The precise approximation of uncertainty in many-valued data set is one of the major tasks. It becomes more difficult in case the given data sets are non-Euclidean. Hence the rough fuzzy set and its graphical visualization is introduced in this paper for knowledge processing tasks. 2022 2022 31 39 10.54216/JNFS.020104 https://www.americaspg.com/articleinfo/24/show/1003
