in this paper by use of mathematical modeling of an observer [14,15] the notion of relative information functional for relative dynamical systemson compact metric spaces is presented. we extract the information function ofan ergodic dynamical system (x,t) from the relative information of t fromthe view point of observer χx, where x denotes the base space of the system.we also generalize the inv...

Knowledge distance is used to measure the difference between granular spaces, which an uncertainty with strong distinguishing ability in a rough set. However, current knowledge failed take relative spaces into account under given perspective of uncertain concepts. To solve this problem, paper studies intuitionistic fuzzy concept (IFC). Firstly, micro-knowledge (md) based on information entropy ...
