      <abstract>
        <p>This document is the preface of the Machine Learning Workshop of the 7th International Conference on Computational Linguistics and Intelligent Systems (CoLInS 2023), April 20The main purpose of the Machine Learning Workshop is a discussion of the recent research results in all areas of Machine Learning Technology for Natural Language Processing and Intelligent Systems Development. The conference is soliciting literature review, survey and research papers comments including, whilst not limited to, the following areas of interest: The language of Machine Learning Workshop is English. The Machine Learning Workshop took the form of oral presentation by peer-reviewed individual papers. The papers were distributed among 93 external reviewers from Portugal, Serbia, Slovenia, Finland and Ukraine. The total number of reviews is 97. To take more correct decision regarding the acceptance or rejection the papers got 3-7 reviews. The peer review statistics is as follows: 21 papers (3 reviews), 1 paper (4 reviews), 1 paper (5 reviews), 3 papers (6 reviews), and 1 paper (7 reviews). ORCID: 0000-0002-9676-0180 (V. Lytvyn); 0000-0002-7404-9638 (A. Kowalska-Stychen); 0000-0001-6417-3689 (V. Vysotska)</p>
