Reference excerpt

Luc Leo Steels (born 22 January 1952) is a Belgian scientist and artist. Steels works with artificial intelligence in Europe who has made contributions to expert systems, behavior-based robotics, artificial life and evolutionary computational linguistics. He was a fellow of the Catalan Institution for Research and Advanced Studies (ICREA) associated as a research professor with the Institute of Evolutionary Biology (UPF/CSIC) in Barcelona. He was formerly founding Director of the Artificial Intelligence Laboratory of the Vrije Universiteit Brussel and founding director of the Sony Computer Science Laboratory in Paris. Steels has collaborated with visual artists and theater makers and composed music for opera.

Biography Steels was born in the town of Belsele near Antwerp, Belgium. He studied German philology at the University of Antwerp, where he obtained a M.A. in 1974 and a Ph.D. in linguistics in 1977 under the supervision of Hugo Brandt Corstius. His thesis was in computational linguistics on a parallel model of parsing. Steels pursued another master's degree in Computer Science at MIT, specializing in AI under the supervision of Marvin Minsky and Carl Hewitt. He graduated in 1979. In 1980, Steels joined the Schlumberger-Doll Research Laboratory in Ridgefield, Connecticut to work on knowledge-based approaches to the interpretation of oil well logging data and became leader of the group who developed the Dipmeter Advisor which he transferred into industrial use while at Schlumberger Engineering, Clamart. In 1983, he was appointed as a tenured professor in Computer Science with a chair in AI at the Free University of Brussels (VUB). The same year he founded the VUB Artificial Intelligence Laboratory and became the first chairman of the VUB Computer Science Department from 1990 to 1995. The VUB AI Lab focused initially on knowledge-based systems for various industrial applications but gradually focused more on basic research in AI. In 1996, Steels founded the Sony Computer Science Laboratory (CSL) in Paris and became its acting director. This laboratory was a spin-off from the Sony Computer Science Laboratory in Tokyo directed by Mario Tokoro and Toshi Doi. The laboratory targeted research in AI, particularly on the emergence and evolution of grounded language and ontologies on robots, the use of AI in music, and contributions to sustainability. The CSL music group was directed by Francois Pachet and the sustainability group by Peter Hanappe. In 2011, Steels became fellow at the Institute for Research and Advanced Studies (ICREA) and research professor at the Universitat Pompeu Fabra (UPF) in Barcelona, embedded in the Evolutionary Biology Laboratory (IBE). There he pursued further his fundamental research in the origins and evolution of language through experiments with robotic agents. From 2018 he started to work in Venice within various European projects, first at Ca'Foscari University within the Odycceus and AI4EU projects and then at Venice International University within the MUHAI project. Throughout his career, Steels had research and educational visits to other institutions. He was a lecturer at the Theseus International Management Institute in Sophia Antipolis, developed courses for the Open University in the Netherlands, was Fellow at the Wissenschaftskolleg in Berlin during the years 2015–2016 and 2009–2010, Fellow at Goldsmiths College London (computer science department) from 2010, visiting scholar or lecturer at La Sapienza University Rome, Politecnico di Milano, the universities of Ghana and Beijing (Jiaotong University) among others. Steels was member of the New York Academy of Sciences, and is elected member of the Academia Europaea, and the Royal Belgian Academy of Arts and Sciences (Koninklijke Vlaamse Academie voor Wetenschappen en Kunsten), where he serves as chairman of the Natural Science section. Steels received several awards including the best paper award at the European Conference in AI (in 1982), the Franqui chair at the University of Leuven (Belgium) (2018), the EurAI Fellowship, the Calewaert chair at the Free University of Brussels (VUB) (2024) and the EurAI Distinguished Service Award, presented every two years to an individual who has made exceptional contributions to the AI community in Europe.

Contributions The scientific work of Steels is trans-disciplinary, focusing on finding conceptual breakthroughs in AI, building the technical tools to work out and develop these breakthroughs, and developing concrete experiments to turn the breakthroughs into viable new AI paradigms. Since the early 1980s and using this approach, Steels has played a role in four profound conceptual shifts: (1) from heuristic rule-based systems to model-based knowledge systems, from model-based to behaviour-based, artificial Life inspired robots, from static, engineered language systems to dynamic, evolving emergent communication systems with features of human languages, and most recently from data-driven AI to AI capable of understanding and forms of awareness.

Worked examples

Example 1 — a first encounter with Luc Steels

Start with the simplest possible case. Write down what Luc Steels claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Luc Steels before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Luc Steels ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Luc Steels

In research: Luc Steels appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Luc Steels in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Luc Steels is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1952 births, Academic staff of Pompeu Fabra University, Academic staff of Vrije Universiteit Brussel, so understanding it makes those chapters shorter.
In everyday life: Look for Luc Steels outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
