Concept Stability as a Tool for Pattern Selection
P. 51–58.
Data mining aims at finding interesting patterns from datasets, where “interesting” means reflecting intrinsic dependencies in the domain of interest rather than just in the dataset. Concept stability is a popular relevancy measure in FCA but its behaviour have never been studied on various datasets. In this paper we propose an approach to study this behaviour. Our approach is based on a comparison of stability computation on datasets produced by the same general population. Experimental results of this paper show that high stability of a concept in one dataset suggests that concepts with the same intent in other dataset drawn from the population have also high stability. Moreover, experiments shows some asymptotic behaviour of stability in such kind of experiments when dataset size increases.

This article is dedicated to designing of the transport and logistics systems with built-in resistance to structural failures. The sustainability indicators reflect the impact of the failure of one or several hubs (communication channels) upon working capacity of the already functioning system. In the process of designing the system, the sustainability indicators also provide opportunities ...

In a seminal paper, Kiparsky & Kiparsky (1970) proposed a two-way correspondence between presuppositionality of clauses and nominal structure. The proposal remains highly relevant to current research (a.o. Kastner 2015, Bochnak & Hanink 2022), despite the existence of counterexamples in both directions. In this paper, we examine Russian nominalized clauses to show that presuppositionality is ...

Emerging adulthood is the youth trajectory characterized by self-focus, identity exploration, feeling between adolescence and adulthood, instability, and experimentation. This trajectory was first identified in industrialized individualistic countries with gender equality and technological progress. To measure transition to adulthood, the Inventory of the Dimensions of Emerging Adulthood (IDEA) was created. Although emerging adulthood is considered ...

In sports games, along with the improvement of motor skills, athletes develop tactical thinking skills – a specialized form of mental activity. This is due to the fact that the absence of standard programs of motor activity in games requires special attention to its current conditions. Therefore, in these sports, the main form of brain ...

The article examines the impact of innovations on the performance of commercial banks. The size of intangible assets is used as a proxy for innovation, since most innovations in the banking sector, unlike those in industry, are intangible and include licenses, software, employees’ knowledge and experience, corporate culture, etc. Most researchers agree that an increase ...

Set partitions and partition lattices are well-known objects in combinatorics and play an important role as a search space in many applied problems including ensemble clustering. Searching for antichains in such lattices is similar to that of in Boolean lattices. Counting the number of antichains in Boolean lattices is known as the Dedekind problem. In ...

In Russian, argument clauses can be nominalized by the demonstrative pronoun to ‘that’ (henceforth, to čto-clauses). Although to čto-clauses have often been discussed in the literature, their distribution is still not fully understood and is subject to conflicting claims, partly owing to the fact that to čto in the accusative/nominative position coincides the “emerging” (noninflected) ...

We study a three-level explicit in time higher-order vector compact scheme, with additional n sought functions approximating second order non-mixed spatial derivatives of the solution, for an initial-boundary value problem for the n-dimensional wave equation and acoustic wave equation, with the variable speed of sound, n⩾1. We also approximate the solution at the first time level in a ...

We consider an initial-boundary value problem for the $n$-dimensional wave equation with the variable sound speed, $n\geq 1$. We construct three-level implicit in time and compact in space (three-point in each space direction) 4th order finite-difference schemes on the uniform rectangular meshes including their one-parameter (for $n=2$) and three-parameter (for $n=3$) families. We also show that some ...

We investigated the stability of silver nanoisland films, which were formed on glass surface by the method of out-diffusion, in biocompatible buffers and the applicability of the films in surface enhanced Raman scattering (SERS). We have shown that silver nanoisland films are stable in one of the most widespread in biological studies buffer—phosphate buffer saline ...

We consider an initial-boundary value problem for the $n$-dimensional wave equation, $n\geq 2$, with the variable sound speed with the nonhomogeneous Dirichlet boundary conditions. We construct and study three-level in time and compact in space three-point in each spatial direction alternating direction implicit (ADI) schemes having the approximation orders $\mathcal{O}(h_t^2+|h|^4)$ and $\mathcal{O}(h_t^4+|h|^4)$ on the uniform rectangular mesh.

We study necessary conditions for stability of a Numerov-type compact higher-order finite-diffe\-rence scheme for the 1D homogeneous wave equation in the case of non-uniform spatial meshes. We first show that the uniform in time stability cannot be valid in any spatial norm provided that the complex eigenvalues appear in the associated mesh eigenvalue problem. Moreover, we prove ...
