Classification Using the Variable Precision Rough Set
In this paper, we present a new version of discernibility matrix, so called variable precision discernibility matrix, which can tolerate the noise of information, in addition, a reduction algorithm is also presented based on the partial order relation of the conditional attribute and used to do image classification. Compared with traditional rough set and BP network, the results will be much be...
متن کاملLattice Structure of Variable Precision Rough Sets
The main purpose of this paper is to study the lattice structure of variable precision rough sets. The notion of variation in precision of rough sets have been further extended to variable precision rough set with variable classification error and its algebraic properties are also studied.
متن کاملMaintenance of Reductsin the Variable Precision Rough Sets
Deenitions of a reduct for a single object, decision class and all objects of decision table for the variable precision rough sets model are introduced. The deenitions have a property that the set of prime implicants of minimal disjunctive normal form of a discernibility function is equal to the set of reducts. Thus the problem of reducts maintenance in dynamically extended information systems ...
متن کاملChemodynamical Simulations of the Milky Way Galaxy
We present chemodynamical simulations of a Milky Way-type galaxy using a selfconsistent hydrodynamical code that includes supernova feedback and chemical enrichment, and predict the spatial distribution of elements from Oxygen to Zinc. In the simulated galaxy, the kinematical and chemical properties of the bulge, disk, and halo are consistent with the observations. The bulge formed from the ass...
متن کاملGalaxy Formation: Clues from the Milky Way
Stellar Populations are the fossil record of Galactic evolution. Interpretation of this record in the Local Group allows one to determine reliably the dominant physics controlling the evolution of those galaxies which are typical of the luminosity in the Universe, and is an essential prerequisite to understanding necessarily limited data at high redshifts. In our Galaxy, the key issues are the ...
