About the Project

Digital technologies have become an important part of our daily routine, impacting the way we interact with people and do business. A more productive and environmentally friendly economy requires a methodical research and innovation strategy and implementation with an integrated vision of the future. However, to fully embrace and enhance the many benefits of this technological revolution, it is critical to address the challenges it poses by creating policies and implementing new solutions that give society the confidence, skills and resources it needs to digitize and grow. Data science and machine learning are players in this technological innovation. Today, companies and organizations have become aware of the importance of using these tools to transform data into a competitive advantage by redefining their products and services.

In recent years, data science has become a priority for our society, as well as for companies, which are investing heavily in this sector. At the basis of any technological innovation is a deep and complete understanding of the fundamental principles that govern it. While data science and machine learning are basically present today in any kind of industrial and technological applications, many constituent aspects of these disciplines are still only partially understood. This has opened a new and very fertile field of research for applied mathematicians who, in recent years, have widely exploited this possibility to develop new branches of pure and applied innovative research. Under this perspective, this project aims to contribute to the green and digital transition by addressing some specific issues in data science and machine learning from the point of view of applied mathematics in the field of energy. On the one hand, we will consider key constitutive aspects of these fields in order to strengthen their mathematical foundations. On the other hand, we will consider practical applications in selected but very relevant problems in fields such as electrical engineering and electrical network design. These applications, related to the integration of distributed generation systems from renewable sources such as photovoltaic, wind or hydroelectric power, represent a priority strategic objective for a more sustainable society of the future.

Summary
Digital technologies are reshaping interactions and business operations, driving the need for a greener strategic approach to research and innovation for more productive economy. To fully leverage the benefits of this technological revolution, it is crucial to address the challenges it poses by creating policies and implementing new solutions that equip society with the confidence, skills, and resources needed for digital growth. Data Science and Machine Learning are the core of this transformation helping organizations gain a competitive edge by redefining products and services as a timely investment for our society and for business and industry. This has opened up a very fertile field of research for applied mathematicians, leading to make new advancements in both pure and applied research strengthening mathematical foundations and practical applications to selected but very relevant problems in areas such as electrical engineering and electrical network design balancing technoligical progress with preparing society for improved sustainability.
