        <p>This document is the preface of the 5th International Workshop on Modern Machine Learning Technologies and Data Science (MoMLeT+DS 2023), June 3, 2023, held in Lviv, Ukraine. The main purpose of the Modern Machine Learning Technologies and Data Science Workshop is o provide a forum for researchers to discuss models for machine learning, multicriteria decision analysis and multi-objective optimization, and their real-life applications. In MoMLeT&amp;DS Workshop, we encourage the submission of papers on machine learning, decision making, multi-objective optimization and multicriteria decision analysis areas. The MoMLeT+DS Workshop is soliciting literature review, survey and research papers comments including, whilst not limited to, the following areas of interest: Gradient Boosted Trees; Support Vector Machines; Unsupervised learning for clustering; MCDM Theory; Multi-objective Optimization; The language of Modern Machine Learning Technologies and Data Science Workshop is English.</p>
