From video games to artificial intelligence, a stopover in Japan
Japan is almost 10,000 kilometers from Belgium, a country that fascinates, not least for its rich culture full of contrasts. Researchers at UNamur maintain close ties with several Japanese institutions, particularly in the fields of computer science, mathematics and video games. Let's take a look at some of these collaborations..

Public defense of doctoral thesis in computer science - Antoine Gratia
Abstract
Deep learning has become an extremely important technology in numerous domains such as computer vision, natural language processing, and autonomous systems. As neural networks grow in size and complexity to meet the demands of these applications, the cost of designing and training efficient models continues to rise in computation and energy consumption. Neural Architecture Search (NAS) has emerged as a promising solution to automate the design of performant neural networks. However, conventional NAS methods often require evaluating thousands of architectures, making them extremely resource-intensive and environmentally costly.This thesis introduces a novel, energy-aware NAS pipeline that operates at the intersection of Software Engineering and Machine Learning. We present CNNGen, a domain-specific generator for convolutional architectures, combined with performance and energy predictors to drastically reduce the number of architectures that need full training. These predictors are integrated into a multi-objective genetic algorithm (NSGA-II), enabling an efficient search for architectures that balance accuracy and energy consumption.Our approach explores a variety of prediction strategies, including sequence-based models, image-based representations, and deep metric learning, to estimate model quality from partial or symbolic representations. We validate our framework across three benchmark datasets, CIFAR-10, CIFAR-100, and Fashion-MNIST, demonstrating that it can produce results comparable to state-of-the-art architectures with significantly lower computational cost. By reducing the environmental footprint of NAS while maintaining high performance, this work contributes to the growing field of Green AI and highlights the value of predictive modelling in scalable and sustainable deep learning workflows.

Artificial intelligence, a danger for democracy?
Can we still speak of democracy when algorithms influence our electoral choices or participate in the drafting of laws? This topic is explored by Aline Nardi, researcher at the Faculty of Law and member of the Namur Digital Institute (NADI).

University and democracy: a living, sometimes threatened, link
Trust of traditional political institutions and elected representatives, rise of authoritarian logics, definition of public services... Democracy today seems to be going through a turbulent zone. What role does the university play in this context? To shed light on this question, we interviewed four researchers from different disciplines: educationalist Sephora Boucenna, philosopher Louis Carré, political scientist Vincent Jacquet and legal scholar Aline Nardi. Their contrasting views sketch out the contours of an issue that is more topical than ever: thinking about and defending the link between university and democracy.

IRDENa Study Day: Training for, by, and within Professional Practice
On May 12, the Institute for Research in Didactics and Education (IRDENa) at the University of Namur is organizing a seminar dedicated to a topic at the heart of current concerns in initial and continuing teacher education: training through professional practice.In a context where expectations of the teaching profession and the realities on the ground are evolving rapidly, and where policymakers are entrusting the field with a significant portion of the training of future teachers through the requirement for extended teaching placements, practical experience plays a decisive role in the development of professional competencies, professional skills, and educational approaches. This essential practice also raises numerous questions:What challenges does training in (with and through) professional practice face today?What obstacles still hinder its implementation or quality?What challenges must training institutions, partner schools, and trainers address?What concrete benefits does professional immersion offer for both aspiring and experienced teachers?To shed light on these questions, the event will feature two speakers:Catherine Van Nieuwenhoven, professor and international expert on teacher education and work-study programs;Sephora Boucenna, a researcher at IRDENa, whose work focuses on professional development through practice and the analysis of field experiences.Their combined perspectives, blending scientific expertise, institutional analysis, and a nuanced understanding of the field, will fuel a collective discussion on the levers to strengthen and the avenues to explore in order to support an ambitious, coherent, and efficient practical training program in light of current policy challenges.The program will continue with a roundtable bringing together colleagues from various universities, who will compare their perspectives on the training of internship supervisors. Their discussion will focus in particular on training needs, support models, institutional challenges, and the conditions necessary to organize this training effectively.Finally, the day will give significant attention to real-world practice through testimonials from several student teachers, who have been invited to share their experiences, their mentoring practices, as well as the tensions that arise in their daily professional lives. These accounts will help ground the discussion in the concrete realities of schools and highlight the importance of the partnership between academic institutions and K-12 education.This study day is intended for researchers, trainers, teachers, as well as anyone involved in teacher education who wishes to contribute to a shared reflection on the future of the profession.
