Abstract
The emerging trend of increasing flexibility, adaptation, and autonomy of control and information systems is the driving force behind the evolving systems paradigm. Evolving systems are characterized with flexible model structure that adjusts to changes which cannot be solely handled by parameter adaptation. Evolving systems develop their structure and knowledge representation through continuous learning from data and interaction with the environment. They exploit synergies between two powerful concepts – real time data granulation and machine learning - with no limitations on the types of the model structure that may include regression models, neural networks, fuzzy, and/or stochastic models. Practical applications encompass a wide range of systems with variable parameters and structure, and multiple operating modes. This presentation provides an overview of the multiple facets of evolving systems theory and describes some of their automotive applications to adaptive process control, automated calibration, anomaly detection, driver state estimation, and fuel economy optimization.

More recently, he is conducting cross-domain research on fault management in interconnected, hybrid and distributed engineered systems using symbolic and abstraction-based methods. Between 2001 and 2015, he had been head of ARIA research team, IMS-lab, CNRS-Bordeaux University. He has authored and co-authored over 75 papers in leading international journals, about 130 communications in international conferences, one Springer book and 12 book chapters. He is a co-holder of 14 patents (French and US) in the aerospace field. He has been coordinator of a number of collaborative French, European and international research projects and actions in control and aeronautics. He is member of TC “Aerospace” and “Safeprocess" of IFAC and Council of European Aerospace Societies. He has served as a program committee member and international advisory board member for various international conferences and has given many invited keynotes, plenary talks and seminaries during international events. He has been member of executive committee of France’s Aerospace Valley Cluster and received an award for excellence in 2010 from the French Aeronautics and Space Foundation. He is the recipient of the 2016 CNRS Innovation Medal for outstanding scientific research with innovative applications in the technological and societal fields.
Abstract
Aerospace has always been a powerful engine of innovation. When we look to the future, it is not obvious to predict where the things are going but there is no doubt that the vector is pointed toward more autonomy and intelligence and that aerospace systems are becoming more distributed and more connected. Nevertheless, the maturity of technologies remains overriding and new unconventional technologies are only adopted if there is a proven need that cannot adequately addressed through conventional employed techniques. Yet, regulatory standards evolve as the industry matures and thanks to new innovative and disruptive technologies and digital transformation, a greater period of innovation is being opened to shape the future of aerospace. The talk will start with the current situation and a look backwards: about a half-century after the early academic works in model-based / data-driven fault management, there exists today a widening gap between advanced academic methods and real-world aerospace applications. The talk will attempt to highlight some of the main reasons for this situation. Next, the talk will argue that for the foreseeable future and given the predicted demands on aviation and aerospace industry, new distributed/cooperative model-based fault management methodologies will be required to enable paradigm shifts in future flight operational issues management. Solutions will arise from cross-domain research at the interface between system & control theory and computer science. Finally, the talk will discuss a future paradigm shift in civil aviation operations toward more autonomy in the cockpit, and some related challenges and opportunities.

Abstract
Despite the recent advancements in Machine Learning and AI, there is an ongoing debate and skepticism in academia as well as in industry with regards to the applicability of AI algorithms to safety critical systems. This skepticism arises from the fact that scientific communities have different standards as to when something works and how often. Another reason for this skepticism is epistemelogical and has to do with the way how communities evolve and pose new scientific questions.
Motivated by this debate, in this talk I will present advancements in the area of autonomy that bridge the gap between the two scientific communities of control and AI. The underlying mathematical principles are at the intersection of stochastic control, statistical physics, machine learning and parallel computing. Inspired from these principles, new algorithms arise for perceptual control that can incorporate physics-priors for both control and perception. In addition, these perceptual control algorithms can be equipped with uncertainty quantification mechanisms for anomaly detection in safety critical. I will conclude this talk with future directions in the areas of safe AI, machine learning and control with applications to autonomy.
