Scalable Estimates of Concept Stability
P. 157–172.
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. Experimental results of this paper show that high stability of a concept for a context derived from the general population suggests that concepts with the same intent in other samples drawn from the population have also high stability. A new estimate of stability is introduced and studied. It is experimentally shown that the introduced estimate gives a better approximation than the Monte Carlo approach introduced earlier.

Fruit trees, cats, and other similar visual stimuli have demonstrated remarkable productivity in experimental research of the Center for Language and Brain, HSE University. Mira Bergelson played a key role in this pear-cat revolution: from introducing the "Pear Stories" film into clinical research to integrating cats into various tools for assessing language production and comprehension. These materials allowed ...

This article investigates the problem of approximating the generalized
Erdélyi-Kober fractional operator (often referred to as the Lowndes operator)
using cubic splines. A method based on cubic spline interpolation
is proposed for approximating the operator on a non-uniform grid. The
convergence rate of the proposed method is proven, and its stability is
analyzed. Error bounds are established for functions in ...

One of the key tasks of hydrogen energy development is to obtain chemically stable proton exchange polymer membranes with high proton conductivity. This article presents the results on the investigation of the stabilization of proton-conducting membranes with a Nafion®-type structure using modification by fluorine. The membranes examined in this study exhibited high thermal stability and ...

Cognitive load theory describes the mechanisms for the transfer of information from human working memory to long-term memory. This theory posits that increasing the number of interactive elements, such as interconnections, may increase cognitive load. This study investigates the impact of interconnections in concept maps on cognitive load, exploring whether they act as interactive elements ...

Recently, the concept of resilience has become very popular in psychological science, which in Russian-language psychology is translated as “zhiznesposobnost” [“viability”] or “ustoichivost” [“stability”]. Despite the fact that this concept has firmly entered the conceptual framework of psychological science, there is still no consensus among researchers on its definition and theoretical load. In the scientific ...

Polybenzimidazoles (PBI) doped with phosphoric acid are a promising electrolyte for medium-temperature fuel cells. However, to be effective at high temperatures in the presence of acid, the mechanical and conductive properties of the material must be stable and no critical increase in gas permeability is required. This work proposes an approach to improve the properties ...

Symbolic markers (as those used in “we-they” attributions) help delineate whether a scientist (among other things) finds themselves at the intersection, within, or outside the confines of a given disciplinary boundary, thereby facilitating the swift navigation across an ever-growing corpus of scientific literature. Frequently, these boundaries are revealed through bibliometric analysis, which makes it possible ...

Various contracts can be designed to coordinate a simple supplier–retailer channel, yet the contracts proposed in prior research and tested in a laboratory setting do not perform as standard theory predicts. The supplier, endowed with all bargaining power, can neither fully coordinate the channel nor extract all of the channel profit. We report on a ...

In the context of the development of text generation technologies, the opposition “naturalness − unnaturalness of text” has been transformed into a new dichotomy: “naturalness – artificiality”. The aim of this article is to investigate the phenomenon of naturalness in this context from two perspectives: analyzing the linguistic characteristics of a natural text against a ...

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 ...

Introduction: Internet of Things devices are actively used within the framework of Massive Machine-Type Communication scenarios. The interaction of devices is carried out by random multiple-access algorithms with limited throughput. To improve throughput one can use orthogonal preambles in the ALOHA-type class of algorithms. Purpose: To analyze ALOHA-based algorithms using the exploration phase and to calculate the characteristics ...
