High Order Singular Value Decomposition for Plant Biodiversity Estimation
High order singular value décomposition pour l'estimation de la biodiversité végétale
High order singular value decomposition per la stima della biodiversità vegetale
Résumé
We propose a new method to estimate plant biodiversity with Rényi and Rao indexes through the so called High Order Singular Value Decomposition (HOSVD) of tensors. Starting from NASA multispectral images we evaluate biodiversity and we compare original biodiversity estimates with those realised via the HOSVD compression methods for big data. Our strategy turns out to be extremely powerful in terms of storage memory and precision of the outcome. The obtained results are so promising that we can support the efficiency of our method in the ecological framework.
