Jun 1, 2023 I gave two talks last week on probabilistic dimension reduction, one at the Séminaire nantais inter-établissements en Science des Données and another during the first animation of the working group LEGO on machine-learning for genomics, which are two very nice research intitiaves! Check the github repos of my slides and code.
Nov 13, 2022 I am glad to give two talks this week, one at the Séminaire Parisien de Statistique and another at ML4 Life Science in Montpellier, both based on this material about recent advances in the Poisson lognormal model
May 16, 2022 The laboratory moved to Palaiseau with all of AgroParisTech to a brand new campus: a few shocks and adjustments on arrival, but all united!
Feb 24, 2022 I have presented Computo at the 2nd Toronto Workshop on reproducibility ! 🤩
Jan 26, 2022 I give an introductory course on Graph Clustering with an accompanying tutorial at Villers-le-lac :sparkles:
