Variational Inference in the Poisson lognormal model for multivariate analysis in ecology
15 février 2018 @ 10:45 – 11:45 – Many application domains such as ecology or genomics have to deal with multivariate count data. A typical example is the joint observation of the respective abundances of a set of species in a series of sites, aiming to understand the co-variations between these species. The Gaussian setting provides a canonical way to model such dependencies, […]
