However, their complexity can lead to risks and failures. Despite modern project management tools improving success rates, significant investment waste and project failures persist. In 2020, 11.4% of investment was lost due to poor project performance, and in 2021, 33% of IT projects failed, resulting in significant budget losses. As organizations enter 2022, challenges in big data, analytics, and AI projects are increasing, highlighting the need for a paradigm change in project management techniques. The Monte Carlo approach, a quantitative risk analysis technique, is gaining popularity to reduce uncertainty in software projects and provide more reliable estimations. The current implementation uses Jupyter Notebooks technology and decreases a steep learning curve for users.Item RECOMMENDATION SYSTEM FOR DATING PROJECTS(2024) Mostovyi, OleksandrThe main functionality for all dating projects is to elevate user experience through the provision of potential matches based on a variety of factors. This project is dedicated to evaluating and comparing the performance of diverse recommendation algorithms within the unique context of dating platforms. As a result an environment consisting of recommendation system and integration into search system of dating application is provided. The evaluation metrics include but are not limited to accuracy, precision, recall, and user satisfaction. By systematically testing these algorithms in controlled scenarios, the research seeks to identify specific performance strengths and weaknesses of each algorithm. Recommendation system is implemented using Python programming language and Flask framework and it uses dataset of profile from dating project. The research also explores the impact of diverse user behaviors and preferences on the recommendation algorithms, providing insights into the adaptability and robustness of each approach. Through a comprehensive analysis, this research aims to contribute valuable insights for dating projects seeking to enhance their recommendation systems. The findings will aid in the informed selection of recommendation algorithms tailored to the specific requirements and dynamics of dating platforms, ultimately improving user experience and satisfaction.Item ExoCoDe: MODELING TRANSITS EVENTS VIA STATISTICAL AND MACHINE LEARNING TOOLS(2024) Karakuts, DenysThis capstone project uses statistical and machine learning algorithms to detect exocomet transits in TESS telescope data. Exocomets, distinguished by their unique, asymmetric light curves, present a detection challenge due to their subtle signatures compared to planetary transits and light intensity. We develop a framework that integrates data preprocessing, feature extraction, visualizations, statistical methods, and machine learning regressors to characterize these transits efficiently. The project is built upon the existing progress of astrophysical research. It aims to enhance our understanding of exocometary activity, uncovering the potential of machine learning and statistical analysis in astronomical data interpretation.Item CUSTOM CRM SYSTEM FOR A LEGAL DEBT COLLECTION COMPANY(2024) Bairaktar, DmytroItem A SUBSYSTEM OF THE INTEGRATION OF THE EDUCATIONAL PORTAL WITH THE LLM-BASE EDUCATIONAL CONTENT GENERATION SYSTEM(2024) Ivchenko, OleksandrLLM models have created a new era of learning and teaching methodologies.

It addresses the gap in research on evolutionary monolithic architectures, introducing the Honeycomb Monolith pattern. This pattern combines Domain-Driven Design with Hexagonal Architecture to create modular monoliths poised for smooth transition to microservices. The effectiveness of the Honeycomb Monolith is demonstrated through the Opora application case study. This implementation validates the pattern viability, showing a seamless migration with minimal impact on the core domain logic. Challenges like model duplication and database management complexities are also identified, underscoring the need for strategic planning in architecture design. Concluding with future research directions, the thesis positions the Honeycomb Monolith as a viable solution for startups and an intermediary step for existing projects transitioning to microservices. This work contributes to the software architecture field, offering a novel solution that balances initial development efficiency with long-term scalability.Item WEB SYSTEM WITH GRAPH UI FOR EXPLORATORY LEARNING(2024) Tytenko, AndriiThis capstone project report details the development of a Graph User Interface application for Exploratory Learning.
