User Need Prediction Based on a Small Amount of User-Generated Content—A Case Study of the Xiaomi SU7
Authors: Liu Lingling , Ma Biao
Published: December 2024

(1) Background: In the current competitive market environment, accurately forecasting user needs is crucial for business success. By analyzing user-generated content (UGC) on social network platforms, enterprises can mine potential user needs and discern shifts in these needs, thereby enabling more efficient and precise product design that aligns with user needs. For newly launched products with a limited presence in the market, the scarcity of UGC poses a challenge to businesses seeking to predict user needs from small datasets. (2) Methods: To address this challenge, this paper proposes a model using correlation analysis (CA) and linear regression (LR) combined with multidimensional gray prediction (a CA-LR-GM (1, N) model) to help enterprises use small sample data to predict user needs. Using the UGC of the Xiaomi SU7 as a case study, this paper demonstrates the prediction of user needs for the vehicle and refines the prediction outcomes through an optimization design informed by the principle of optimal key feature distribution. (3) Results: The findings validate the feasibility of the proposed theoretical framework, offering a technical solution for the identification and prediction of user need trends. (4) Conclusions: This research puts forward strategic recommendations for enterprises regarding the optimization of their products.

“Tenho mais cadastro em farmácias do que em baladas”: rastros de discursos medicalizantes em enunciados de sujeitos homossexuais masculinos no Twitter
Authors:   , Cabral Cláudio Orlando Gamarano
Published: December 2024

Esta tese, produzida junto ao PPGE/Faced/UFJF na linha de pesquisa Discurso, Práticas, Ideias e Subjetividades em Processos Educativos, é o desdobramento de um trabalho de pesquisa cujo objetivo foi problematizar a forma como discursos medicalizantes marcam a sociedade ocidental e atravessam a produção de homossexualidades masculinas nos dias atuais. As problematizações que compõem os textos desta tese foram conduzidas a partir da consideração foucaultiana de que os discursos acerca do sexo e da sexualidade ocupam lugar central na produção de sujeitos na sociedade ocidental, isto é, no sexo são encontradas “as verdades mais secretas e profundas do indivíduo”, ocorrendo essa produção de sujeitos atravessada pela medicalização. Com referência nas possibilidades de análises que as teorizações pós-críticas, incluindo os estudos de gênero e os estudos culturais sob as perspectivas pós-estruturalistas, os estudos queer e as suas aproximações com os estudos foucaultianos inspiram, este estudo utilizou o conceito de medicalização para se referir a um processo indefinido e crescente que, em nossos dias, transfere, para a ciência biomédica e farmacêutica, poderes que vão muito além do tratamento de doenças, transtornos ou incômodos que possam afetar o corpo, ou seja, um poder que se estende a toda a vida. Utilizando como campo de pesquisa enunciados de sujeitos que participam do Twitter, esta pesquisa investigou, e buscou atualizar, a forma como se construiu (e se constrói) uma marca de anormalidade e doença que ainda está presente quando pensamos nas práticas sexuais e afetivas entre pessoas do mesmo gênero. Para tal intuito, investiu-se na análise do discurso de inspiração foucaultiana, para problematizar os discursos que atravessam, via medicalização, a constituição das homossexualidades, a fim de investigar como alguns discursos vêm funcionando como instrumento estratégico de normalização da sociedade, engendrando, especialmente, condutas e comportamentos de determinados corpos homossexuais masculinos. A partir dos objetivos propostos, este trabalho, ao considerar que nos constituímos sujeitos por variados processos educativos, aponta para a grande importância das redes sociais, dentre elas o Twitter, como poderosas maquinarias de produção de sujeitos, corpos e sexualidades em nossos dias; uma produção que acontece por meio da circulação de discursos e enunciados que a profusão de formas de interação entre sujeitos que o Twitter e as redes sociais, de maneira geral, possibilitam.

Correlación del comportamiento de una arquitectura de red LoRaWAN con modelos de propagación en un entorno con vegetación
Authors:   , Jaszczyszyn Adrián
Published: December 2024

Las redes LPWAN son redes inalámbricas de bajo consumo de energía y largo alcance que se utilizan principalmente para conectar dispositivos de Internet de las Cosas (IoT) a internet. En el ámbito de la agricultura, IoT está transformando el futuro de la industria mediante la implementación de técnicas de agricultura inteligente o de precisión y una forma de lograr esto es mediante la tecnología LoRa con arquitectura de red LoRaWAN en las prácticas agrícolas tradicionales. Esto permite mejorar el manejo, la comprensión y control de las áreas de cultivo, lo que a su vez aumenta la eficiencia y la productividad. Sin embargo, en este proceso de transmisión de datos en la agricultura, pueden surgir obstáculos como la misma vegetación de los cultivos, los cuales afectan la calidad de la señal a lo largo de su recorrido. Para abordar este problema, hay modelos empíricos que consideran la pérdida de atenuación de la señal debido a la vegetación, a los cuales también se les debe agregar las pérdidas no relacionadas a la flora. Este trabajo tiene como objetivo el armado de una infraestructura de red con tecnología LoRaWAN en una institución pública de la zona núcleo de la provincia de Buenos Aires, para analizar y evaluar el comportamiento con modelos de la propagación de datos en un entorno rural con vegetación. La implementación brinda una solución a la creciente demanda de IoT como así también, la oportunidad de interacción entre las distintas áreas dentro de la institución. Además, ofrece soporte para las actividades de investigación, educativas y el desarrollo de nuevas soluciones.
Sobre circunferências e pontos médios na geometria da epsilon-métrica da soma
Authors: Bambarén Edwin Pedro López , Chávez Newton Mayer Solórzano , Garcia Dik Dani Lujerio
Published: December 2024

In this work, the authors perturb the metric of addition by adding a linear map that depends on a perturbation parameter epsilon, with 0 <= epsilon < 1. This new way of measuring distances in the Cartesian plane is called the epsilon-metric of addition. It is shown that the epsilon-metric of addition is non-negative and satisfies the triangle inequality, but it is not symmetric. Thus, a new non-Euclidean geometry is introduced. Both circles and midpoints are defined and classified in this new geometry. Two types of circles and more than one point that can be called a midpoint are obtained. Examples, graphs, and geometric interpretations are presented for a better understanding.

Formação continuada e cultura digital: a discussão sobre a integração de saberes tecnológicos e pedagógicos nas teses brasileiras
Authors: Do Amaral Teixeira Luciana , Alves de Oliveira Maria de Fátima
Published: December 2024

This study investigates the integration of technological and pedagogical knowledge in the continuing education of teachers, focusing on the promotion of digital culture in educational practices. The objective is to analyze, through a Systematic Literature Review (SLR), how Brazilian theses address this theme and what challenges and opportunities are identified in this process. The methodology adopted involves the selection and analysis of theses defended in Brazilian postgraduate programs and listed in the CAPES Theses and Dissertations Catalog, which allows for an understanding of the approaches taken and the existing gaps in continuing education aimed at the incorporation of Information and Communication Technologies (ICT). The results reveal that, despite significant advances, many teachers still face challenges in adopting ICT in their practices, particularly due to resistance to new methodologies, the rapid pace of technological change, and unequal access. It is concluded that continuing education needs to be rethought to include more flexible and collaborative strategies, enabling teachers to adapt more effectively to the demands of digital culture. The study suggests that future research should focus on international comparisons and the application of the TPACK model, as well as investigate the sustainability of pedagogical practices acquired over time.

Authors: Maeda Tatsuro , Ishii Hiroyuki , Chang Wen Hsin , Takagi Komei , Shibayama Shigehisa , Kurosawa Masashi , Nakatsuka Osamu
Published: December 2024

The Ge0.75Sn0.25 alloy, which is lattice matched to the InP, has the potential to create a high-quality GeSn-on-insulator (GeSnOI) structure for group IV optoelectronic devices. A Ge0.75Sn0.25OI metal-semiconductor-metal (MSM) photodetector was fabricated through the layer transfer technique using DiVinyl Siloxane bis-Benzocyclobuten (DVS-BCB) polymer as an adhesive and highly selective wet etching of InP substrate over GeSn, Si, SiO2 and DVS-BCB. The photoresponse of the Ge0.75Sn0.25OI MSM photodetector at a wavelength of 1550 nm was evaluated using a modulated laser and lock-in method, achieving a responsivity and a noise equivalent power (NEP) of ∼3 × 10−6 A W−1 and ∼1 × 10−6 W/Hz0.5, respectively. The thermal budget for fabricating Ge0.75Sn0.25OI MSM photodetector is below 220 °C, which is compatible with conventional Si back-end-of-the-line (BEOL) processing toward three-dimensional (3D) heterogeneous-integrated devices.
Enhanced reliability of ferroelectric Hf0.5Zr0.5O2 capacitors by bottom electrode surface oxidation
Authors: Itoya Yuki , Saraya Takuya , Hiramoto Toshiro , Kobayashi Masaharu
Published: December 2024

We demonstrate that ozone oxidation of the bottom TiN electrode surface in Hf0.5Zr0.5O2 (HZO) ferroelectric capacitors enhances dielectric-breakdown (DB) lifetime and endurance. Time-dependent-dielectric-breakdown measurements and Weibull analysis reveal the crystalline states in HZO on the oxidized bottom electrode surface influence on DB lifetime. First-order reversal curve analysis shows uniform polarization reversal voltage with oxidation. Grazing incidence X-ray diffraction indicates significant changes in crystallographic orientation, while X-ray photoelectron emission spectroscopy reveals minimal changes in interfacial chemical bonding states. This ozone oxidation forms a chemically uniform interfacial layer on the bottom electrode, promoting out-of-plane aligned crystallization, thus mitigating weak breakdown points for DB and endurance fatigue.

Flexibility and equality: Unraveling the nexus of labor market dynamics and gender equality in developing countries
Authors: Jomaa Hajer
Published: December 2024

Recent decades have witnessed notable advancements in gender equality. However, improvement in labor market outcomes remains limited especially for women. On the other hand, regulations related to the labor market have shifted toward greater flexibility. This study investigates the relationship between labor market flexibility and gender equality, aiming to uncover the impact of flexible employment strategies on social inequality. Utilizing cross-country regression models, we analyze the correlation between labor market flexibility indicators and wage equality for a similar work index across 99 developing countries in 2021. The findings indicate that three of the examined indicators exhibit a robust positive correlation with the dependent variable. This suggests that increased flexibility in these areas would potentially reduce gender disparities. Focusing on a wide sample of developing countries, the research implications provide valuable insights for policymakers seeking to address the gender gap in the labor market and promote equal opportunities.
Innovative cooling solutions of HPDC technology
Authors: Bratu Zoltán Ferenc , Erdélyi János Péter , Molnár Dániel
Published: December 2024

In High Pressure Die Casting (HPDC), the so-called sliders are moving components of the mould, that can form cavities, holes, and undercuts. Sliders differ greatly from fixed- and moving mould halves regarding cooling and thermal balance. Typically, mould halves can range from a few hundred kilograms to several tonnes in size, whereas sliders have a significantly lower mass, and therefore their thermal balance changes much more drastically during casting cycles. Sliders can also be used to improve local heat dissipation in different areas. They are equipped with cooling holes through which the hole-forming cores, which penetrate deep into the mould cavity, can be tempered so that a significant amount of heat can be removed from the solidifying metal during the mould-filling process. As the industry produces increasingly complex castings, the cooling systems for the various moulds, inserts and cavities have evolved accordingly as the complexity of the castings has increased. This has resulted in innovative solutions and developments in the cooling of moulds and mould inserts, such as the use of 3D-printed metal inserts with improved heat dissipation. This article compares the cooling differences between traditionally cooled and 3D-printed sliders. We investigate cooling efficiency and tool temperatures at different cooling intensities through simulation experiments. Furthermore, at the end of the solidification phase, we examine the mold temperatures and the heat extracted for different molds and cooling intensities.
The effect of RSW technological parameters to the properties of aluminium/steel hybrid joints
Authors: Fodorné Cserépi Mariann , Meilinger Ákos
Published: December 2024

To reduce fuel consumption and costs, the lightweight construction of car bodies is a very important aspect. This is achieved by using high-strength steel and aluminium alloy base materials. The latest car bodies contain both steel and aluminium alloy, so it is necessary to develop a reliable joining technology between them. Several joining technologies were investigated, such as mechanical joining, adhesive joining, and welding too. Resistance spot welding (RSW) is typically used to join car body parts and can be used for aluminium/steel hybrid joints. During welding, a very brittle intermetallic compound (IMC) is formed, which basically determines the properties of the joint, which is particularly influenced by the thickness and phases of the IMC. EN AW 5754 H22/ DP600 dissimilar joints were made with RSW, using different welding parameters. The joints were tested by shear-tensile tests and the effect of the IMC layer was determined.

Impact of Russian full-scale military invasion on vulnerable socio-demographic groups in Ukraine: problems, consequences and solutions
Authors: Kurylo Iryna , Aksionova Svitlana
Published: December 2024

The situation with vulnerable people attracted considerable attention of the government and society in Ukraine even in pre-war times. Important steps taken to improve this situation were destroyed first by the pandemic of COVID-19, and then by the war. The purpose of this study is to determine current problems of vulnerable socio-demographic groups in Ukraine that are caused by russian full-scale military invasion and to define the consequences and possible solutions. In the analysis we used the requests for help received by the Red Cross phone hot line, the feedback from volunteers and people who needed help, forums of volunteers and online publications. The work used comparisons, statistical methods and analysis of telephone interviews. It was found, that the most frequent and important was request for medicine. The large share of vulnerable populations was at risk of not receiving critical health care and medicine. Many elderly people suffered from regular bombings and absence of electricity, water and ood. It was a huge challenge to organize the evacuation of elderly people and particularly people with disabilities to relatively safe regions. The health and social support systems in Ukraine are facing exceptional challenges and pressure. The support of volunteers became extremely important. The further destiny of all people and predominantly vulnerable sociodemographic groups in Ukraine will largely depend on whether the whole world can unite to resist Russian aggression.
Трансформация белорусской семьи на современном этапе развития
Authors: Bobrova Anastacia
Published: December 2024

The article examines the process of transformation of the family institution in Belarus. Over a hundred years, the Belarusian family has undergone radical changes. As many specialists point out, there has been a transition from a patriarchal (traditional) multi-generational large family to an egalitarian, nuclear, small family. A comparison of the results of the 2009 and 2019 censuses reveals the main current challenges for the family institution: an increase in the number of singles, a decrease in the number of families, a decline in the number of married couples with underage children, and a reduction in the average family size. Positive trends include an increase in the number of children in households with underage children and an increase in the proportion of households with three or more children. One of the main challenges to demographic security is the reluctance to have children. According to census data, women's plans to have children have been assessed. Differentiation in birth planning across the country's districts has been identified. Based on the available demographic data and the results of the 2019 census, a typology of administrative districts of Belarus by the family structure and reproductive potential has been developed. The typology is based on the principles of rating and the main priorities of demographic security of the Republic of Belarus. Most districts in the Republic of Belarus are characterised by an average level of family structure and reproductive potential. The largest concentration of districts with a transitional type with above-average family structure and reproductive potential indicators is located in Brest, Gomel and Minsk regions.
An evaluation on the effects of the Covid-19 pandemic on the world tourism economy
Authors: Eşitti Buket Buluk
Published: December 2024

The Covid-19 pandemic, which was first identified at the beginning of January 2020, is a major health crisis that has affected the whole world for more than two years. While the Covid-19 pandemic caused the biggest economic crisis of the century on a global scale, tourism is one of the sectors most negatively affected by this process. In this study, by giving general information about the Covid-19 pandemic, the effects of the pandemic on the world tourism economy were examined. Accordingly, in the study, situation of tourism before the pandemic and during the pandemic period and the effects of the pandemic on the world tourism economy were examined based on secondary data. In this context, reports, documents and previous studies on this subject were scanned with the literature review method in the study. As a result of the examination, it was determined that the Covid-19 pandemic has deeply affected the world tourism economy in the tourism seasons of 2020 and 2021. However, in this process, it was seen that countries do not want to lose their income from tourism activities due to the economy and other factors measures have been taken by supporting the tourism sector with many financial, consultancy, and supportive packages, especially taxes. Finally, it was seen that tourism professionals predicted that the year of 2022 will be the year of recovery in the tourism sector compared to the previous two years. Based on these results obtained as a result of the study and the view that 2022 will be the year of recovery in the tourism sector compared to the previous two years, inferences were made about what kind of structural changes will occur in the tourism sector. In this context, it is thought that the study will also guide tourism practitioners as well as its contribution to tourism literature.

Discuții privind pragurile de îndatorare și legătura dintre datorie și creștere economică
Authors: Milea Camelia
Published: December 2024

Public debt has increased significantly in most countries in the last 3 years as a result of the global crisis that has begun in 2020 in the context of the outburst of covid-19, and of the effects of the measures adopted by the authorities in order to stop the spread of the disease. In this context, the author aims to analyze what is the level of debt beyond which it is no longer sustainable, and it becomes a burden for the debtor economy, as well as the factors that influence this level. The article6 explains what the debt threshold is. Next, it is shown, based on economic literature, the elements that exert influence on debt thresholds, but also what are the factors on which depend the effects of public debt on economic growth. The notion of debt threshold is used by some researchers to describe a level of debt to GDP beyond which debt no longer supports economic growth, but it has negative effects on economic growth. The methodology used consists of comparative and descriptive analyses, literature review.

Authors: Luchian Ivan , Filip Angela
Published: December 2024

At the moment, the investment process in the Republic of Moldova is taking place under the conditions of an unfavorable market situation both at the international and national level. The main purpose of the study was to determine the basic trends of the development of the investment process in the Republic of Moldova. For this, official databases and reports of authorized public institutions were examined. In the same way, the opinions of experts in the given field were studied. The study was conducted on the basic aspects of investment activity: investment in fixed assets, foreign investment, capital market investment opportunities, and investment in free economic zones. During the pandemic crisis, the investment activity in the Republic of Moldova decreased, and currently an important relaunch of the investment activity and a continuation of the attraction of foreign investments can be observed. But until now, an important problem remains the qualitative orientation of the investment activity; the placements in the country's productive sectors remain at an insufficient level. The capital market in the Republic of Moldova continues to have an underdeveloped character. In addition to this, under the conditions of the crisis, its development continued, with the main segment remaining the state securities market. One of the elements of the investment policy of the Republic of Moldova is to ensure the continuity and development of the activity of free economic zones, the liquidation of which is foreseen by the Association Agreement between the European Union and the Republic of Moldova.
Investigație privind o eventuală manipulare a dobânzilor interbancare ROBOR
Authors: Vasilca Miruna , Vid Alin Ioan , Anton George
Published: December 2024

Recently observers have expressed concerns that the ROBOR benchmark
interest rates may not accurately reflect the costs of interbank lending.
ROBOR rates are reference indices for variable interest loans granted to both
individuals and corporate clients, but also for derivative financial contracts that has
ROBOR as the underlying asset. Therefore, the impact of ROBOR's relevance is
reflected in a much wider range of financial products addressed to the population,
which will bear all the changes related to its volatility. Therefore, the importance of
the evolution and variation of this index is indisputable from the perspective of end-consumers of banking products.
This paper examines a possible manipulation of the prices of interbank
deposits. In order to evaluate the evolution of the relevant ROBOR rates from the
perspective of the existence of a market manipulation behaviour, for the period July
2, 2018 - April 4, 2022, two scenarios were analysed: i) a cartel agreement colluded
between two or more participants in order to obtain an additional financial income
related to the loan portfolio indexed to ROBOR; respectively ii) a cartel agreement
colluded between two or more participants in order to use inside information
regarding the monetary policy decisions of the National Bank of Romania (NBR).
Analysing the hypotheses of the two scenarios, we conclude that there are no
indications of a possible manipulation of ROBOR interest rates by tacit agreements
between participants at Fixing or by using inside information on monetary policy
decisions of the NBR.

Published: December 2024

The paper presents in the introductory part an analysis of the need and opportunity of the circular economy. The second part addresses the energy universe in which the opportunities of mankind are abundant and attractive due to the revolution of industrial technologies. Inseparable from resources, from the preindustrial period to the present, technologies have evolved in leaps and bounds. The four great industrial revolutions are defined, found in the literature as Industry 1.0, 2.0. 3.0 and 4.0, characterized by energy metamorphosis. Two primordial chemical elements are analyzed - C and H2, which have irreversibly changed the economies and craft societies through industrialization, electrification, digitalization and interconnectivity (global cyber-energy networks), in conditions of carbonization of energy. The third part presents the concept of the Geoenergetic landscape, in which new economies and "energy smart societies" are preparing for a new leap, an industrial revolution based on hydrogen technology (hydrogenation of energy).
Instrumente financiare de reducere a riscurilor in economia circulară
Authors: Dodu Aliona
Published: December 2024

The circular economy aims to reduce overconsumption, restore and regenerate ecosystems and design-out waste. Waste management has historically been financed by the public sector and, in particular, by municipal governments. New financial instruments and investments are needed to support the growth of the circular business models. In order to develop circular business models, it is important to know their financing possibilities and the financial products and services, including public equity funds, bonds, private market funds and banking. Investments in circular economy and new business models, especially in developing countries, are still considered to be high risk compared to ongoing and growing finance experiments in industrialized economies. Private sector capital is urgently needed as current levels of development financing are not sufficient. A number of derisking instruments could be applied to finance circular economy projects and provide access to funds for SMEs in developing countries. The author identified four instruments such as loan guarantee schemes, political risk insurance, public equity co-investments and public–private blended finance as potential instruments for derisking and scaling up investments for circular solutions. This article represents an exhaustive research that is part of the project State Program 2020-2023, "Development of the circular economy formation mechanism in the Republic of Moldova, with code 20.80009.0807.22.

The paper analyzes the complex interaction between testimony and individual perception, highlighting inequalities and inhomogeneities of social environments that influence witnesses' capacities and motivations. Witness statements, a fundamental tool of evidence, are examined in the context of the judicial process, where the main objective is to discover the truth. The importance of removing barriers that can distort information is emphasized, including the use of appropriate psychological tactics and methods in interrogations. Throughout history, the value of testimony has been the subject of debate, being recognized as relative and susceptible to errors and subjective influences. Psychologists and lawyers have investigated the phenomenon of memory and recognition, highlighting its fragility and the influence of contextual factors. Currently, the evaluation of testimony involves careful consideration of the sincerity and veracity of witnesses, in the context in which they may be affected by stress, pressure or other external influences. In addition, the paper examines the phenomenon of perjury, highlighting its social and legal implications. In conclusion, understanding the relativity of testimony is essential in the judicial process, and its proper approach can help ensure justice and prevent miscarriages of justice.
Charity and Global Solidarity - A Dying Idealism?
Authors: Wall Stig
Published: December 2024

This opinion piece raises concerns about whether solidarity can remain broad or will narrow to self-interest-driven initiatives, compounded by current aid policies linking assistance to trade benefits and redirecting development funds closer to home.
My Rotary group took on a project supporting the Galkayo Education Center for Peace and Development (GECPD) in Somalia, founded by women’s rights activist Hawa Aden Mohammed. The project, driven by her vision, emphasized education for girls, addressing inequalities tied to poverty and cultural practices like female genital mutilation. Over three years, we funded a teaching position and covered school fees for underprivileged students. By connecting local and global actions, this effort exemplifies how solidarity can transcend geographical and cultural divides. Working in such initiatives not only contributes to social change but also offers personal growth, underscoring the enduring value of innovative engagement models in an evolving world.
Ensuring financial stability of mechanical engineering in the context of sectoral and technological sanctions
Authors: Ivanova Lyudmila , Motorov Vladimir
Published: December 2024

The article discusses the indicators of the activities of the enterprises of the mechanical engineering industry of the Russian Federation that are significant in the context of ensuring the financial stability of its enterprises. An assessment of the dynamics of changes in these indicators allowed the authors to conclude that the financial and economic state of this industry has been consistently deteriorating in recent years. An analysis of the industry structure of mechanical engineering in the Russian Federation in 2023 showed that a significant share of the products manufactured here remains dependent on imported components and technologies. This circumstance, according to the authors, indicates the need to focus the attention of the state policy aimed at ensuring the financial stability of the domestic mechanical engineering cluster on solving the problems of import substitution, and also that such a policy itself should be based on measures that can ensure the development and implementation of solutions in the field of ensuring the financial security of individual enterprises of the industry cluster, and built on the same principles.

Published: December 2024

According to the national goal “Technological Leadership” of the Russian Federation, neural network modeling of the current state of socio-economic activity of small businesses in the subjects of the country from the perspective of innovative development and digital transformation was carried out. Entrepreneurial activity, one of the types
of which is small business, refers to one of the initiative forms of socio-economic development of the Russian Federation and ensuring its technological sovereignty and technological leadership. Small business activates the development of innovative solutions, contributing to strengthening the economic security of the country. The paper considers and examines the data of the Federal State Statistics Service for 2023. Cluster analysis is performed using a new promising methodological approach — neural networks, which make up one of the significant components of artificial intelligence. The clustering
of data was carried out on the basis of self-organizing artificial neural networks using information technologies according to 7 indicators certifying the innovative component and digital transformation in the activities of small businesses in the subjects of Russia. The following regions of the Russian Federation are not involved in the study: Donetsk People’s Republic, Luhansk People’s Republic, Zaporizhia and Kherson regions due to the lack of selected indicators on the website of the Federal State Statistics Service. The ranking of the subjects of the Russian Federation in five clusters was obtained. The composition and characteristics of each cluster are presented. The conducted research using neural network technologies made it possible to determine the features of innovative development and the state of digital transformation of small businesses in the subjects of the country. The results of the study contain a practical orientation and can be taken into account in the strategic planning of small business development in the context of increasing coordination of strategies for its innovation activities and strategies of the state, related to the dominant internal factors of the socio-economic potential of the Russian Federation in order to strengthen the technological leadership
of the Russian Federation.
