24 novembre 2020 : Prix Monpetit (Académie des Sciences)     
Je remercie respectueusement l'Académie des Sciences pour cette distinction.
Je remercie chaleureusement tous mes collègues (de France et du monde), et tous mes étudiants pour ces belles années de travail ensemble.

September 2020: Artist Residence at SiSyPh
          
Alex Andrik, an artist interested in relations between Art and Sciences, spent three weeks interacting with Team SiSyPh discussing Signal processing: here is the outcome, https://vimeo.com/464170699
He had previously attended GRETSI2019, the French speaking Signal and Image Processing Conference, interacting with attendee, which yielded: https://vimeo.com/357425722
Spring 2020 (lockdown period): Team SiSyPh fighting COVID

Spatial and temporal regularization to estimate COVID-19 Reproduction Number R(t)
-
  • Publication dans The Conversation d'un article court et grand public sur la surveillance de la pandémie de Covid19.
  • Credibility intervals for the estimates of R (stochastic sampling in Bayesian frameworks). 
  • New research paper, dealing with outliers and estimation robustness to the low quality of Covid19 data, submitted in Sept. 2021.
  • Research paper, accepted for publication at PLoSOne
  • video for the evolution along time and across France of R(t)
  • Daily summary for estimations, credibility intervals, graphics and maps.

based on: new infections, new hospitalizations,   per department and  time evolution
(new release (2021/04/11: interactive and animated map of France for the daily estimates of R)

Most recent estimates of R for Metroplitan France available here

Maps and Global estimates for the World and for the USA, for estimated R(t) based on new infections
(see also a nicer World map of the daily estimates of R)
New release (2021/04/11):  interactive and animated map of the World-Covid19-R !!
