  1. Blind outlier detection inatmospheric inverse problems By Marta

  2. LCAV/EPFL

  3. Atmospheric Inverse Problems: problem setup LCAV/EPFL

  4. Ground truth: ETEX • European Tracer Experiment (ETEX), France, 1994. • 340 Kg of PMCH were released at a constant rate during 12 hours. • Nowadays it is forbidden to perform this kind of experiments! LCAV/EPFL

  5. Additive noise LCAV/EPFL

  6. Improvement when the outliers are removed (manually) LCAV/EPFL

  7. RANdomSAmpling Consensus LCAV/EPFL

  8. Improved metric LCAV/EPFL

  9. Voting step LCAV/EPFL

  10. TRANSAC LCAV/EPFL

  11. Performance LCAV/EPFL

  12. Performance LCAV/EPFL

  13. Next steps • Get CAPTEX dataset • Apply TRANSAC to greenhouse gasses emissions • Robust statistics • In particular, principal components regression and partial least squares regression LCAV/EPFL
