Hector Geffner is an ICREA Research Professor at the Department of Information and Communication Technologies, UPF. He obtained a BSc on Electrical Engineering at the Universidad Simon Bolivar in Caracas, and a MSc in Systems Science and a PhD in Computer Science at the University of California, Los Angeles (UCLA). After his PhD, he worked at the IBM T.J. Watson Research Center in NY, USA from 1989 until 1992, and at the Universidad Simon Bolivar, in Caracas, from 1992 until 2001. He also taught at Stanford University, Aachen University of Technology, Linkoping University, Universite Paul Sabatier, and the University of Edinburgh, among other places. Since 2001 he has been at the UPF in Barcelona, as an ICREA Research Professor where he heads the Artificial Intelligence (AI) group.
Hector works on planning and plan recognition in intelligent systems, developing methods for generating and recognizing autonomous behavior automatically using model-based methods. In these methods, agents are not programmed by hand, but rather derive their behavior by solving a model of the interaction between the agent, the environment, and possibly other agents. One of the main challenges in planning is computational as these models are all intractable in the worst case, and algorithms must be able to automatically recognize and exploit the structure of problems. The work involves logical and probabilistic models, domain-independent heuristics and algorithms, and computational experiments.
Hector's research is relevant to both artificial intelligence and cognitive science, as it aims to uncover general principles of rational behavior that take into account the computational constraints that are present in both natural and artificial systems. While his main interests are in AI and Cognitive Science, he is also quite interested in the Human and Social Sciences. He is currently involved in several funded research projects, basic and applied, including a Consolider Project about Simulating the Past that involves a number of archeologists; an European Project, Spacebook, for developing speech-driven, hands-free, eyes-free devices for pedestrian navigation and exploration, and a National I+D Project, about robust and scalable model-based methods for the generation of autonomous behavior.
Hector Geffner is the recipient of the 1990 ACM Dissertation Award, and is best known for the heuristic search approach to planning for which he received the 2009 and 2010 ICAPS Influential Paper Awards. He is a fellow of both the American and the European Association for Artificial Intelligence (AAAI, ECCAI), and Associate Editor of the two top AI journals: Artificial Intelligence (AIJ), and the Journal of Artificial Intelligence Research (JAIR). He is professionally involved in many of the top AI conferences, having served in recent years as Area Chair for IJCAI, AAAI, ECAI, UAI, and KR, and as co-chair of ICAPS. Hector is the author of the book Default Reasoning, MIT Press, 1992, and co-editor with Rina Dechter and Joseph Halpern of the book 'Heuristics, Probability and Causality: A Tribute to Judea Pearl', College Publications, 2010. He is currently the Director of the UPF Master on Intelligent Interactive Systems.
Anders Jonsson is a Lecturer in the Department of Information and Communication Technologies at Universitat Pompeu Fabra (UPF). He is a native of Stockholm, Sweden. He received his MSc in Engineering Physics from the Royal Institute of Technology in Stockholm, and his Ph.D. in computer science from the University of Massachusetts Amherst. He joined UPF in 2005 as a visiting lecturer and member of the Artificial Intelligence group.
Anders' main research interest is devising automatic techniques for solving sequential decision problems in the form of either reinforcement learning or artificial intelligence planning. In particular, his focus is finding and exploiting the structure of such problems in order to simplify their solution. This structure can take many forms, but usually manifests itself either as abstract
states, in which the same solution holds for several different situations, or abstract actions, in which actions can be grouped together in a hierarchy. He is also interested in analyzing the computational complexity of solving different classes of sequential decision problems.
Anders also enjoys developing artificial intelligence solutions for real-world applications. During the past few years he has been involved in several research projects, both at the national and international level. He has also published several papers in prestigious international journals and serves on the programming committee of a number of international conferences.
Apart from research in artificial intelligence, Anders really enjoys programming, and for the last five years he has served as coach of the UPF programming team at the Southwestern Europe Regional Contest, part of the ACM International Collegiate Programming Contest.
Leo Wanner is an ICREA Research Professor at the Department of Information and Communication Technologies, UPF. Leo earned his Diploma degree in Computer Science from the University of Karlsruhe, Germany and his PhD in Linguistics from the University of The Saarland, Saarbrücken, Germany. Prior to joining DTIC as ICREA Research Professor, he held positions at the Institute for Integrated Publication and Information Systems of the German National Centre for Computer Science in Darmstadt, University of Waterloo, the University of Stuttgart and the Institute for Applied Linguistics (IULA), UPF. As a visiting researcher, he was also affiliated with the University of Montreal, University of Sydney, University of Southern California's Institute for Information Sciences, and the Columbia University, New York.
Leo works in the field of computational linguistics, teaching the computer how to supply people with information that might be useful to them in their language and how to serve as interpreter between people who do not speak a common language. His research foci include automatic multilingual report generation, automatic summarization of written material and paraphrasing. He is furthermore interested in computational lexicology and lexicography, and there, in particular, in the recognition, representation and use of lexical idiosyncrasies by language learners.
Throughout his career, Leo has been involved in various large scale national, European, and transatlantic research projects. He has published five books and over 100 refereed journal and conference articles. He also serves as regular reviewer for a number of high profile conferences and journals.
