Preface It is our pleasure to present you the proceedings of the MoMLeT&DS Workhop of the 10th Inter- national Conference on “Mathematics. Information Technologies. Education”, the first edition of the Modern Machine Learning Technologies and Data Science Workshop, held in Lviv-Shatsk (Ukraine) on June 5-6, 2021. The main purpose of the MoMLeT&DS Workhop is to provide a forum for researchers to discuss models for machine learning, multicriteria decision analysis and multiobjective optimization, and their real-life applications. In MoMLeT&DS 2021, is encourage the submission of papers on machine learning, decision making, multiobjective optimization and multicriteria decision analysis areas. Nov- el applications of these methods to real world problems are welcome. The conference is soliciting literature review, survey and research papers comments including, whilst not limited to, the following areas of interest:  Regression analysis;  Multiobjective Optimization;  Deep learning;  Group Decision Making;  Gradient Boosted Trees;  Multiattribute Utility or Value Theory;  Support Vector Machines;  Behavioral Issues in Decision Making;  Bayesian networks;  Preference Modelling;  Unsupervised learning for clustering;  Applications of MCDM and  MCDM Theory; Optimization. The language of MoMLeT&DS Workshop is English. The conference took the form of oral presentation by invited keynote speakers plus presentations of peer-reviewed individual papers. There was also an exhibition area for poster and demo sessions. A Student section of the conference for stu- dents and PhD students runs in parallel to the main conference. The conference took the form of oral presentation by invited keynote speakers plus presentations of peer-reviewed individual papers. The papers were distributed among 47 external reviewers from France, The Netherlands, United King- dom, Poland, Indonesia, India, Germany, Czech Republic, Portugal, Kingdom of Saudi Arabia and Ukraine. The total number of reviews is 145. To take more correct decision regarding the acceptance or rejection the papers got 2-5 reviews. The conference gathered participants from different countries including India, Kazakhstan, Morocco, Ukraine and Netherlands. This year the Organizing Committee received 63 submissions, out of which 48 were accepted for presentation as regular papers. The papers are submitted to the following tracks: Regression analysis (3 papers); Deep learning (5 papers); Gradient Boosted Trees (6 papers); Support Vector Machines (3 papers); Bayesian networks (3 papers); Unsupervised learning for clustering (3 papers); MCDM Theory (9 papers); Multiobjective Optimization (6 papers); Group Decision Making (7 papers); Mul- tiattribute Utility or Value Theory (5 papers); Behavioral Issues in Decision Making (6 papers); Pref- erence Modelling (3 papers); Applications of MCDM and Optimization (15 papers). These papers and extended abstracts were published in this Volume of MoMLeT&DS Workshop 2021 proceedings. The conference would not have been possible without the support of many people. First of all, we would like to thank all the authors who submitted papers to MoMLeT&DS 2021 and thus demonstrated their interest in the research problems within our scope. We are very grateful to the members of our Program Committee for providing timely and thorough reviews and, also, for being cooperative in doing additional review work. We would like to thank the Organizing Committee of the conference whose devotion and efficiency made this instance of MoMLeT&DS a very interesting and effective scientific forum.
