      CALLAHAM, Jared L.; BRUNTON, Steven L.; ccLOISEAU, Jean-Christophe (Cambridge University Press (CUP), 2022-03)
      This work investigates nonlinear dimensionality reduction as a means of improving the accuracy and stability of reduced-order models of advection-dominated flows. Nonlinear correlations between temporal proper orthogonal ...

      CALLAHAM, J. L.; RIGAS, G.; BRUNTON, S. L.; ccLOISEAU, Jean-Christophe (The Royal Society Publishing, 2021-06)
      Many physical systems characterized by nonlinear multiscale interactions can be modelled by treating unresolved degrees of freedom as random fluctuations. However, even when the microscopic governing equations and qualitative ...

      CHEHAB, Omar; DEFOSSEZ, Alexandre; GRAMFORT, Alexandre; KING, Jean-Remi; ccLOISEAU, Jean-Christophe (Neurons Behavior Data Analysis and Theory (NBDT), 2022-10)
      Understanding how the brain responds to sensory inputs from non-invasive brain recordings like magnetoencephalography (MEG) can be particularly challenging: (i) the high-dimensional dynamics of mass neuronal activity are ...

      ccLOISEAU, Jean-Christophe (Springer Science and Business Media LLC, 2020-07)
      Identifying accurate and yet interpretable low-order models from data has gained renewed interest over the past decade. In the present work, we illustrate how the combined use of dimensionality reduction and sparse system ...

      SANSICA, Andrea; KANAMORI, Masashi; HASHIMOTO, Atsushi; ccLOISEAU, Jean-Christophe; ccROBINET, Jean-Christophe (American Institute of Aeronautics and Astronautics (AIAA), 2022-02)
      When modeled within the unsteady Reynolds-Averaged Navier-Stokes framework, the shock-wave dynamics on a two-dimensional aerofoil at transonic buffet conditions is char- acterized by time-periodic oscillations. Given the ...
    • Chapitre d'ouvrage scientifique
      BRUNTON, Steven; NOACK, Bernd; ccLOISEAU, Jean-Christophe (De Gruyter, 2021-06)
      Reduced-order models are essential for the accurate and efficient prediction, estimation, and control of complex systems. This is especially true in fluid dynamics, where the fully resolved state space may easily contain ...

      KAPTANOGLU, Alan; DE SILVA, Brian; FASEL, Urban; KAHEMAN, Kadierdan; GOLDSCHMIDT, Andy; CALLAHAM, Jared; DELAHUNT, Charles; NICOLAOU, Zachary; CHAMPION, Kathleen; KUTZ, J.; BRUNTON, Steven; ccLOISEAU, Jean-Christophe (The Open Journal, 2022-01)
      Automated data-driven modeling, the process of directly discovering the governing equations of a system from data, is increasingly being used across the scientific community. PySINDy is a Python package that provides tools ...
