Identifying Non-Sublattice Equivalence Classes Induced by an Attribute Reduction in FCA
Mathematics, 2021 The detection of redundant or irrelevant variables (attributes) in datasets becomes essential in different frameworks, such as in Formal Concept Analysis (FCA).

Galois Connections between Semimodules and Applications in Data Mining [PDF]
, 2007 In [1] a generalisation of Formal Concept Analysis was introduced with data mining applications in mind, K-Formal Concept Analysis, where incidences take values in certain kinds of semirings, instead of the standard Boolean carrier set.

Toward a Broader Understanding: A Formal Concept Analysis of the Micropolitics of a School
Acta Paedagogica Vilnensia, 2018 [full article in English] The micropolitics of a school is one of the key factors that determine changes in member interactions in a learning organization and requires a careful study in order to create a favorable school environment.

Simplifying Implications with Positive and Negative Attributes: A Logic-Based Approach
Mathematics, 2022 Concepts and implications are two facets of the knowledge contained within a binary relation between objects and attributes. Simplification logic (SL) has proved to be valuable for the study of attribute implications in a concept lattice, a topic of ...

The algebraic structure of morphosyntactic features
Nordlyd: Tromsø University Working Papers on Language & Linguistics, 2015 The most common way of separating homophony from syncretism — which is a basic challenge for any inflectional analysis: to distinguish between accidental and systematic form-identity — is attributing only the latter to a coherent feature combination ...

Strategies for Student Evaluation in The Online Context
Studia Universitatis Babes-Bolyai: Series Informatica, 2021 In this paper we conducted an investigation on the performance of the students during the second semester of the academic year 2020-2021. We looked at the performance results obtained by students on the laboratory work, practical and final exams while ...

FEBS Letters, EarlyView.Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Formal Context Transforms and Their Affordances for Exploratory Data Analysis
MathematicsConsider a formal context (G, M, I) as the basic mechanism to capture information about a set G of objects, a set M of attributes and the relation I ∈ G × M between them. Traditional use of Formal Concept Analysis has some shortcomings in its information-

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
