Title: Recent Advances in the Deep Learning Approach in Control and Mobile Robotics
Designing controllers for tasks with complex nonlinear dynamics is extremely challenging, time-consuming, and in many cases, infeasible. This difficulty is intensified in tasks such as mobile robotics tool handling, in which dynamics might vary both with environmental properties, such as material and tool class, and with time while acting. This plenary speech aims at drawing attention to recent deep learning methods applications in control systems as well as to equivalent Reinforcement learning (RL) approaches offering efficient ways to control nonlinear stochastic systems with partly or even fully unknown dynamics. Recent advances in areas such as deep learning and adaptive dynamic programming (ADP) have led to significant developments in applications from robotics, automotive systems, smart grids, game playing, traffic control, etc. This talk will attempt to provide a comprehensive outline and the principal algorithms of novel contributions at the cutting edge of deep learning and RL as well as ADP for control systems, addressing open issues such as performance guarantees, computational complexity, large-scale systems, multiagent or partially observable problems, etc. We will try particularly to pay attention to the, so far largely unidentified, interfaces between artificial/computational intelligence and control-theoretic approaches to deep learning, RL and ADP technologies and suggest a framework and ways for designing such hybrid control systems with applications especially to mobile robotics.
Dimitrios A. Karras received his Diploma and M.Sc. Degree in Electrical and Electronic Engineering from the National Technical University of Athens, Greece in 1985 and the Ph. Degree in Electrical Engineering, from the National Technical University of Athens, Greece in 1995, with honours. From 1990 and up to 2004 he collaborated as visiting professor and researcher with several universities and research institutes in Greece. Since 2004, after his election, he has been with the Sterea Hellas Institute of Technology, Automation Dept., Greece as associate professor in Digital Systems and Signal Processing as well as with the Hellenic Open University, Dept. Informatics as a visiting professor in Communication Systems (the latter since 2002 and up to 2010). He has published more than 65 research refereed journal papers in various areas of intelligent systems, pattern recognition, image/signal processing and neural networks as well as in bioinformatics, communications and business modelling. He has published more than 180 research papers in International refereed scientific Conferences in the above fields. His research interests span the fields of intelligent systems, pattern recognition and neural networks, image and signal processing, image and signal systems, biomedical systems, communications, networking, security and management sciences/business intelligence. He has served as program committee member in many international conferences, as well as program chair and general chair in several international workshops and conferences in the fields of signal, image, communication and automation systems. He is, also, former editor in chief (2008-2016) of the International Journal in Signal and Imaging Systems Engineering (IJSISE), academic editor in the TWSJ, ISRN Communications and the Applied Mathematics Hindawi journals as well as associate editor in various scientific journals. He has been cited in more than 1808 research papers, his H/G-indices are 18/42 (Google Scholar) and his Erdos number is 5. His RG score is 30.70 ( profile/Dimitrios_Karras2/). Finally, he is a senior business consultant since the last ten years.
