To determine the main precursory anomalies from intricate earthquake precursors in given area is the important content of earthquake consultation. Based on the dynamic transfer characteristic of elements in S-rough sets theory, and the regional difference and precursory difference of earthquake precursory anomalies, an analytical algorithm of earthquake precursory anomalies based on two direction...
S-rough sets (singular rough sets) theory was proposed by improving Z.Pawlak rough sets theory. S-rough set has dynamic characteristics, since it is defined by R -element equivalence class[x] which has dynamic characteristic. The concept of rough data was presented by employing S-rough sets, and rough data has dynamic characteristic, furthermore, the rough data law generation is given. Based on the...
Function S-rough sets (function singular rough sets) has function (law) characteristic and dynamic characteristic. Function one direction S-rough sets (function one direction singular rough sets) is one of the three forms of function S-rough sets. By employing function one direction S-rough sets, this paper presents F-decomposition concept of image, F-decomposition theorem of image, F-decomposition...
For dynamic system law mining, according to function two direction S-rough sets, this paper presents the concepts of law generation and F-law relation metric; by using these concepts, this paper proposes characteristic theorem of F-rough law relation metric, dependence theorem of F-rough law relation metric, the principle of F-rough law discovery and gives the application of F-rough law in profit...
Function one direction S-rough sets (function one direction singular rough sets) is defined by R-function equivalence class. A function is a curve or a line. Function one direction S-rough sets has curve characteristics and dynamic characteristics. By using function one direction S-rough sets, the concept of image F-interior hiding is presented; the theorem of image F-interior hiding and the recognition...
