Clustering Based on Data Envelopment Analysis: Application to Management Research and Practice
P. 142–145.
Kuskova V., Zaytsev D.
Data Envelopment Analysis (DEA), a linear programming technique, is becoming increasingly popular in management studies. A variety of extensions have been proposed since its first introduction in the late 1970s, and lately, the idea of using the tool for clustering data has received some attention in the literature. We have further extended the idea of DEA-based clustering by introducing the notion of clustering by DEA-generated vector, with some useful applications in non-homogeneous samples, data with unclear theoretical structure, or as an explanatory tool. We demonstrate how these techniques can be used in management on a sample from education industry.

The article considers one of the most famous examples of socio-economic systems characterized by significant uncertainty—the S&P-500 stock market, where shares of 500 largest US companies are traded. The flexible algorithm for daily trading has been developed. It is based on known fixed data about cost of shares in previous days as well as on ...

Periods of high market volatility put investors in a situation where conventional decision- making methods are less reliable. To improve returns, market participants need to understand which factors play a big role in portfolio formation. This article analyzes the determinants of Russian stock returns during the Covid-19 and the rise in geopolitical tension in 2022. ...

We propose a novel method for rapid pattern analysis of high-dimensional numerical data, termed tunnel clustering. The main advantages of the method are its relatively low computational complexity, endogenous determination of cluster composition and number, and a high degree of interpretability of final results. We present descriptions of three different variations: one with fixed hyperparameters, ...

The concept of Z-number was proposed by Prof. Lotfi Zadeh to describe partial reliability of information, and it is a kind of fusion of fuzziness and probabilistic uncertainty. Z-number can be presented as a pair of fuzzy numbers Z(A,B) used to describe a value of a random variable X. The first component (A) is a ...

Community detection in attributed networks aims to recover clusters in which the within-community nodes are as interconnected and as homogeneous as possible, while the between-communities nodes are as disconnected and as heterogeneous as possible. The current research proposes a straightforward data-driven model with an integrated regularization term to recover communities. For further improvement of the ...

Clustering has always been in great demand by scientific and industrial communities. However, due to the lack of ground truth, interpreting its obtained results can be debatable. The current research provides an empirical benchmark on the efficiency of three popular and one recently proposed crisp clustering methods. To this end, we extensively analyzed these (four) ...

Кластерный анализ широко используется в различных научных и практических областях, связанных с анализом данных. Это важный инструмент для решения задач в таких областях, как машинное обучение, обработка изображений, распознавание текста и т.д. Отсутствие наблюдений не всегда означает отсутствие информации, поэтому предполагается, что наличие пробелов в данных, наличие“пустых” кластеров, также несёт в себе информацию об объекте исследования, как и реальные наблюдения. В этом исследовании предполагается, ...

Geolectal variation is often present in settings where one language is spoken across a vast geographic area. This can be found in phonological, morphosyntactic, and lexical features. For practical reasons, it is not always possible to conduct fieldwork in every single location of interest in order to obtain the full pattern of variation, and a ...

This paper summarizes practices of customer-driven services applied in the leading Russian bank to avoid the impact of financial sanctions (2014–2019). We show how economic sanctions and strict national policies triggered this bank to increase flexibility in customer care to attract more capital from their existing clients. The project comprised three stages: (1) to analyse ...

In the vicinity of the type-I/type-II crossover in conventional superconductors, vortices exhibit a nonmonotonic interaction, which leads to exotic vortex matter states. We perform molecular dynamics simulations on a model superconductor in the intertype regime. In a field cooled approach, we examine the transition of a homogeneous vortex lattice (VL) into a structure consisting of ...
