data analysis


In the modern world of scientific and technological progress, the requirements for the accuracy and reliability of measurements are becoming increasingly stringent. The rapid development of machine learning (ML) methods opens up perspectives for improving metrological processes and enhancing the quality of measurements. This article explores the potential application of ML methods in metrology, outlining the main types of ML models in automatic instrument calibration, analysis, and prediction of data.

Features of Recommendation Algorithm on Base of Analysis of Social Network Data Mining Methods

In recent years, social media platforms have become powerful data collection tools to improve user experience. The vast amount of data generated through social media provides a unique opportunity to develop innovative recommendation systems. This article analyzes the application of data mining methods for social networks in the context of effective recommendation systems, focusing on three key methodologies: sentiment analysis (SA), topic modeling (TM) and social network analysis (SNA), highlighting their positive features.


The increasing demand for precision agriculture has prompted the integration of advanced technologies to optimize agricultural practices. This article presents an approach to agricultural field data processing using a cloud-based data pipeline. The system leverages data from various sensors deployed in the fields to collect real-time information on key parameters such as soil moisture, temperature, humidity, etc. The collected data is transmitted to the cloud where it undergoes a series of data processing and analysis stages.

Principles of constructing a software system of the aggregated data formation

This paper is devoted to the principles of constructing a software system of the aggregated data formation. The main principles of constructing a software system of the aggregated data formation are considered and their comparative analysis are carried out. An alternative principle of constructing a software system is proposed. This principle of constructing allows to eliminate the problems of fast and reliable data processing, scaling, automation of the software system components, improve data quality and security.

Обчислювальні аспекти аналізу даних на основі карт Кохонена

The trends of the past decade in architecture of the central processing unit show a clear direction towards multi-core processors with the number of cores increasing every eighteen months according to the Moore’s law. The shift from fast single-core to slower multi-core CPUs poses a question of scalability for a vast class of computational algorithms including algorithm used for data analysis. This paper presents the research result of using state of the art parallelisation programming paradigms to scale data analysis processes based on Self-Organising Maps.

Візуалізація даних, кластеризованих динамічно-інтервальною самоорганізовною картою

In this article we present an algorithm for visualising the clustering structure of the data model captured by dynamic interval self-organising map (DISOM). The developed visualisation algorithm employs the Self-Organising Map for placing DISOM elements on the 2D lattice in conjunction with U-Matrix algorithm for visualization of data clusters.
