A system for classifying the sentiment of Ukrainian news headlines using deep learning methods is presented and two LSTM-based neural network models are developed: one trained on a small manually-labeled Ukrainian text corpus, and another trained on a larger Twitter-based English corpus that was machine-translated into Ukrainian. A comparative evaluation of these models’ performance is conducted, and observations are made about language-specific challenges in sentiment expression for Ukrainian. The advantages and limitations of each approach are discussed and directions for further research in multilingual sentiment analysis are outlined.</p> 2025-06-30T00:00:00+00:00 Copyright (c) 2025 https://icsfti-proc.kpi.ua/article/view/338757 AI DRIVEN LOG ANALYSIS IN COMPLEX SYSTEMS 2025-09-07T13:10:20+00:00 Oleksand Pankratov oleksandrpankratov40@gmail.com <p><span style="font-weight: 400;">The article presents an overview of existing approaches to the application of various AI models and methods for log analysis in complex systems.

The key feature of the proposed approach is the use of bitwise modifiers to encrypt individual bits of the binary representation of the signal. This technique enables lightweight and flexible encryption on terminal devices, significantly complicating unauthorized reconstruction of the signal during processing on a remote computing system. A thorough theoretical analysis and experimental modeling were conducted, demonstrating that the developed method achieves a 1–2 orders of magnitude increase in processing speed compared to traditional schemes, while maintaining a high level of data confidentiality. The proposed solution is suitable for secure and efficient image processing in cloud environments, particularly in scenarios with limited computational resources on the terminal side.</p> 2025-06-30T00:00:00+00:00 Copyright (c) 2025 https://icsfti-proc.kpi.ua/article/view/338740 METHOD OF USING CLOUD SERVICES IN COMBINATION WITH CI/CD FOR THE SMART CITY SYSTEM 2025-09-07T12:02:05+00:00 Iryna Klymenko klymenko.iryna@lll.kpi.ua Viktoriia Babenko babenko.viktoriia@lll.kpi.ua <p>The article explores the feasibility of implementing cloud services in combination with continuous integration and delivery (CI/CD) technologies for the development of a flexible and scalable Smart City system.
