Interesting Concept Mining With Concept Lattice Convolutional Networks

open access: yesIEEE Access
The extraction of meaningful conceptual structures is often a critical task in many scientific and engineering disciplines, as it enables a comprehensive analysis of complex data in terms of both context and content.

Attribute Reduction in Soft Contexts Based on Soft Sets and Its Application to Formal Contexts

open access: yesMathematics, 2020
We introduce the notion of the reduct of soft contexts, which is a special notion of a consistent set for soft contexts. Then, we study its properties and show that this notion is well explained by the two classes, 1 0 and 2 0 , of ...

Research of ontology construction of coal mining face based on formal concept analysis

open access: yesGong-kuang zidonghua, 2017
In view of problem of time-consuming and subjective dependence of traditional ontology construction method, an ontology construction method of coal mining face based on formal concept analysis was proposed.

Hesitant Fuzzy Concept Lattice and its Application

open access: yesIEEE Access, 2020
The hesitant fuzzy set (HFS) can reflect the hesitation and uncertainty of decision-makers for the reason that it uses some possible values instead of a certain value. Considering that there is still no research on concept lattice or fuzzy formal concept

Gradation of Fuzzy Preconcept Lattices

open access: yesAxioms, 2021
Noticing certain limitations of concept lattices in the fuzzy context, especially in view of their practical applications, in this paper, we propose a more general approach based on what we call graded fuzzy preconcept lattices.

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

On Concept Lattices for Numberings

open access: yesTsinghua Science and Technology
The theory of numberings studies uniform computations for families of mathematical objects. In this area, computability-theoretic properties of at most countable families of sets S are typically classified via the corresponding Rogers upper semilattices.

On inference rules in decision formal contexts [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2015
Rule acquisition is one of the main purposes in the analysis of decision formal contexts. In general, the number of implications in a decision formal context is an exponential increase to the scale of the database.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
