Research of data mining methods for classification of imbalanced data sets

With the rapid development of information technology, which is widely used in all spheres of human life and activity, extremely large amounts of data have been accumulated today. By applying machine learning methods to this data, new practically useful knowledge can be obtained. The main goal of this paper is to study different machine learning methods for solving the classification problem and compare their efficiency and accuracy.

Conceptual Approach to Detecting Deepfake Modifications of Biometric Images Using Neural Networks

The National Cybersecurity Cluster of Ukraine is functionally oriented towards building systems to protect various platforms of information infrastructure, including the creation of secure technologies for detecting deepfake modifications of biometric images based on neural networks in cyberspace. 

This space proposes a conceptual approach to detecting deepfake modifications, which is deployed based on the functioning of a convolutional neural network and the classifier algorithm for biometric images structured as “sensitivity-Yuden index-optimal threshold-specificity”.

MEAT QUALITY RESEARCH USING CLASSIFICATION ALGORITHMS

The food industry is going through constant improvements and is subject to analyzing consumer needs, product quality research is essential to striking this balance. In this regard, meat quality, the most essential food category, should be studied with unbiased methods that give precise and correct results. Classification algorithms are considered one of the main components of developing an objective and reliable method of meat quality assessment.

Силуети кольору та яскравості зображень для їх класифікації та пошуку

Для зменшення часових затрат пошуку зображень у базах даних великих розмірів запропоновано підхід, що ґрунтується на визначенні силуетів яскравості зображень різних типів: фронтального та бічного для двох видів яскравості. Подальше приско- рення пошуку відбувається за рахунок заміни кривих силуетів поліноміальними функціями чебишовського типу. Додатковою ознакою є відстань до піків силуетів. Як приклади практичних даних використано зображення із відомих баз образів. Критеріями прийняті силуети та відстані до них.

On the publicly dangerous content of military administrative offenses

Abstract. Consideration of the provisions related to administrative illegality aimed at encroachment on social relations involves the analysis of its main components and causes of its occurrence in normal conditions of the functioning of society, as well as in special conditions to which the legal regime of martial law belongs. The complexity of the socio-economic and political situation in Ukraine led to the introduction of martial law by the President of Ukraine (February 2022) due to military aggression by the Russian Federation.

Tactical planning methods: meaning and typology in the system of circular business models of enterprises

Purpose. The concept of circular economy (closed-loop economy) emerged as an alternative economic model designed to reduce the negative impact on the environment, solve the problem of resource scarcity, extend the life cycle of products and solve global problems of the world economy and international economic relations on this basis. Obtaining the benefits of implementing circular business models, which consist in increasing the income of the world economy, saving resources, and increasing the number of jobs, requires reasonable and rational planning at enterprises.

Methods and means of determining objects of radio intelligence using the ontological approach

The article is devoted to the study of methods and means of determining objects of radio technical intelligence using machine learning technologies and an ontological approach. A naіve Bayesian classifier was used to identify objects of radio technical intelligence. The Naive Bayes classifier is a machine learning algorithm used to classify objects based on probabilities. In this article, a naive Bayesian classifier is used to determine the classes to which objects of radio technical intelligence belong.

STRATEGIC ENVIRONMENTAL ASSESSMENT - UNDERESTIMATED TOOL FOR SUSTAINABLE SUBSOIL USE

Strategic environmental assessment is an effective tool for improving the level of environmental safety in various areas. The purpose of the article is to identify and classify the main tasks of strategic environmental assessment in subsoil use, taking into account its role and functions in the subsoil management system, and to suggest ways to improve environmental safety in subsoil use by means of strategic environmental assessment.

THE ESSENCE AND TYPES OF TOOLS FOR ECONOMIC PROTECTION OF THE ENTERPRISES IN INTERNATIONAL ACTIVITY

Purpose. The action of the tools for economic protection of the enterprise is aimed at ensuring the state of economic security, characterized by the absence of threats to the external and internal environment. In the context of globalization and development of international economic relations, protection of economic interests and processes of enterprises is aimed at maintaining its stable function, protection of intellectual property, guaranteeing the inviolability of property, protection of information and interests of stakeholders in general and more.

Research into machine learning algorithms for the construction of mathematical models of multimodal data classification problems

Currently, machine learning algorithms (ML) are increasingly integrated into everyday life. There are many areas of modern life where classification methods are already used. Methods taking into account previous predictions and errors that are calculated as a result of data integration to obtain forecasts for obtaining the classification result are investigated. A general overview of classification methods is conducted. Experiments on machine learning algorithms for multimodal data are performed.
