Attribute Reduction Algorithm of the Lattice-Valued Concept Lattice

Li Yang, Yuhui Wang, Yang Xu

Abstract



This paper, based on the lattice implication algebra, proposes the lattice-valued concept lattice, which can be used to depict the uncertainty relation between objects and attributes. In order to improve the processing efficiency, we research the attribute reduction theory and the judgment theorems of the lattice-valued concept lattice and give an attribute reduction algorithm. The implementation of this algorithm is simple and easy to operate, and in the end, an illustrative example is employed to show the application of the proposed reduction algorithm.

We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information. Also: DOI is paid service which provided by a third party. We never mentioned that we go for this for our any journal. However, journal have no objection if author go directly for this paid DOI service.
