The focal point for this year’s conference was machine learning and applications. The need for machine learning is ever growing due to the increased pervasiveness of data analysis tasks in almost every area of life, including business, science, and technology. Not only is the pervasiveness of data analysis tasks increasing, but so is their complexity. These tasks usually need to handle massive datasets which can be partially labeled. The datasets can have many input and output dimensions, streaming atveryhighrates.Furthermore,thedatacanbeplacedinaspatio-temporalornetwork context. Machine learning is continuously unleashing its power in a wide range of appli- cations including marketing, e-commerce, software systems, networking, telecommu- nications, banking, finance, economics, social science, computer vision, speech recognition,naturallanguageprocessing,robotics,biology,transportation,healthcare, and medicine. The information explosion has resulted in the collection of massive amountsofdata.Thisamountofdata,coupledwiththerapiddevelopmentofprocessor power and computer parallelization, has made it possible to build different predictive models. These predictive models can study and analyze complex data in various application areas to discover relationships in data to inspire insights and create opportunities, identify anomalies and solve problems, anticipate outcomes, and make better decisions. Some of these topics were brought to the forefront of the ICT Innovations 2020 conference.Thisbookpresentsaselectionofpaperspresentedattheconferencewhich contributedtothediscussionsonvariousaspectsofmachinelearningandapplications. The conference gathered 146 authors from 14 countries reporting their scientific work andsolutionsinICT.Only18paperswereselectedforthiseditionbytheInternational Program Committee, consisting of 163 members from 45 countries, chosen for their scientific excellence in their specific fields. We would like to express our sincere gratitude to the invited speakers for their inspirational talks, to the authors for submitting their work and sharing their most recent research, and the reviewers for providing their expertize during the selection process. Special thanks go to Bojana Koteska and Monika Simjanovska for the tech- nical preparation of the conference proceedings.
