MATHEMATICAL MODEL OF ERRORS IDENTIFICATION IN TEXTS OF UKRAINIAN CONTENT

The problem of automated error detection in Ukrainian texts is becoming particularly relevant in the context of the growth of digital content. A mathematical model of a decision support system for detecting errors in Ukrainian-language texts has been developed. The process of error identification has been studied as a multi-class classification task at the token level, considering the context of the text. The use of probabilistic models has been proposed to determine the type of error depending on the environment of tokens in the text.

PREDICTION OF INDUSTRIAL EQUIPMENT CONDITION USING COST-SENSITIVE APPROACHES AND CLASSIFICATION THRESHOLD OPTIMIZATION

This paper presents a comprehensive study on the application of modern machine learning methods for predictive maintenance based on the open AI4I Predictive Maintenance dataset. The primary goal of the research is to develop and compare both binary and multiclass classification models that enable not only the prediction of machine failures but also the identification of specific failure types.

Information Theory in Multi-Label Feature Selection: An Analytical Review

In the context of multi-label learning, feature selection (MLFS) is a key process for handling high-dimensional datasets, aiming to retain the most informative features while preserving inter-label relationships.  This study presents an extensive overview of state-of-the-art MLFS approaches founded on principles from information theory.  The paper first introduces the fundamental concepts of information theory, then provides a detailed review of representative MLFS methods along with their theoretical background.  Performance assessments are carried out on real-world mu

Hybrid Behavioural Analysis Method for Early Detection of Anomalous Activity in Web Applications

The research introduces a hybrid behavioural analysis technique for early detection of anomalous user behavior observed on web applications. This strategy involves statistical probability modeling and sequence- based deep learning to design interpretable and robust anomaly detection. A probability baseline has been obtained as a probabilistic basis using KDE (Kernel Density Estimation) and longitudinal time series patterns are sampled using an LSTM network. The hybrid anomaly score combines these two models to dynamically analyze behavioural deviations.

MACHINE LEARNING-BASED PREDICTION OF ELECTRIC VEHICLE REMAINING RANGE WITH CONSIDERATION OF BATTERY DEGRADATION

Accurate prediction of the remaining driving range in electric vehicles (EVs) is critical for efficient trip planning, reducing the risk of battery depletion, and improving user experience. One of the significant challenges in achieving high prediction accuracy is battery degradation, which gradually reduces battery capacity and impacts the vehicle’s range. This study uses machine learning algorithms to investigate the impact of incorporating battery degradation—expressed through the State of Health (SoH) indicator—into range prediction models.
