Didier Sornette is Professor on the Chair of Entrepreneurial Risks in the Department of Management, Technology and Economics at ETH Zurich. He also holds a position at the Swiss Finance Institute, and several other departments at ETH Zurich (Physics, Earth Sciences). Prof. Sornette is a founding member of the Risk Center at ETH Zurich and has published 500+ research papers and 7 books. In 2008, he founded the Financial Crisis Observatory to diagnose and predict financial bubbles. His research focuses on the predictability and control of crises and extreme events in complex systems with particular focus on financial bubbles, crashes, earthquake physics and geophysics, the dynamics of success on social networks and the complex system approach to medicine towards the diagnostic of systemic instabilitiesPresentation Overview
 The ‘endo-exo’ problem in complex systems (ecology, earthquakes, financial volatility, epileptic seizures…)
AbstractThe “endo-exo” problem — i.e., decomposing system activity into exogenous and endogenous parts — lies at the heart of statistical identification in many fields of science. E.g., consider the problem of determining if an earthquake is a mainshock or aftershock, or if a surge in the popularity of a youtube video is because it is “going viral”, or simply due to high activity across the platform. The “endo-exo” problem is also at the heart of a general description of the dynamics of out-of-equilibrium complex systems generalising the fluctuation-susceptibility theorem. There will be 45-minute presentation, followed by a 45-min Q&A.
