Identifying knowledge gaps in biodiversity data and their determinants at the regional level
Didier Alard, Anaïs Guéry
Biodiversity open-access databases are valuable resources in the structuring and accessibility of species occurrence data. By compiling different data sources, they reveal the unev…
Evaluating multi-season occupancy models with autocorrelation fitted to heterogeneous datasets
André Luís Luza, Didier Alard, Frédéric Barraquand
Predicting species distributions using occupancy models accounting for imperfect detection is now commonplace in ecology. Recently, modeling spatial and temporal autocorrelation wa…
Estimating Canopy Height at Scale
Jan Pauls, Max Zimmer, Una M. Kelly +6
We propose a framework for global-scale canopy height estimation based on satellite data. Our model leverages advanced data preprocessing techniques, resorts to a novel loss functi…
Extension of Correspondence Analysis to multiway data-sets through High Order SVD: a geometric framework
Olivier Coulaud, Alain Franc, Martina Iannacito
This paper presents an extension of Correspondence Analysis (CA) to tensors through High Order Singular Value Decomposition (HOSVD) from a geometric viewpoint. Correspondence analy…
A geometric view of Biodiversity: scaling to metagenomics
Pierre Blanchard, Philippe Chaumeil, Jean-Marc Frigerio +5
We have designed a new efficient dimensionality reduction algorithm in order to investigate new ways of accurately characterizing the biodiversity, namely from a geometric point of…
diagno-syst: a tool for accurate inventories in metabarcoding
J. -M. Frigerio, F. Rimet, A. Bouchez +6
Metabarcoding on amplicons is rapidly expanding as a method to produce molecular based inventories of microbial communities. Here, we work on freshwater diatoms, which are microalg…
