Textural dependency and concept lattices

S Bayhan - International Journal of Approximate Reasoning, 2021 - Elsevier
In this paper, the dependence spaces are discussed for textural formal concepts considering
the method given by Ma et al. A complete congruence on a complete lattice is an …

Textural unit operations in rough set theory

M Diker, AA Uğur, S Bayhan - Information Sciences, 2017 - Elsevier
In this study, we introduce a textural counterpart of the unit operation of Wybraniec-
Skardowska. A unit di-operation has two parts which are called a unit co-operation and a …

Textures and dynamic relational systems

AA Uğur - International Journal of Machine Learning and …, 2018 - Springer
Dynamic relational systems have different forms in literature of rough set theory. They are
divided into two parts by Pagliani as synchronic and diachronic dynamics. Synchronic …

[HTML][HTML] Dicovering approximation spaces and definability

M Diker, AA Uğur - International Journal of Approximate Reasoning, 2018 - Elsevier
In this work, we define a category Cap of covering approximation spaces whose morphisms
are functions satisfying a refinement property. We give the relations among Cap, and the …

Textures and rough sets

M Diker - Handbook of Neural Computation, 2017 - Elsevier
It is known that approximation operator and definability are two main tools in rough set
theory. These tools are also key concepts for texture spaces. The aim of this chapter is to …
