Diagonal Nonlinear Transformations Preserve Structure in Covariance and Precision Matrices
Rebecca E Morrison, Ricardo Baptista, Estelle L Basor
For a multivariate normal distribution, the sparsity of the covariance and precision matrices encodes complete information about independence and conditional independence propertie…
Bayesian Optimization of Combinatorial Structures
Ricardo Baptista, Matthias Poloczek
The optimization of expensive-to-evaluate black-box functions over combinatorial structures is an ubiquitous task in machine learning, engineering and the natural sciences. The com…
Beyond normality: Learning sparse probabilistic graphical models in the non-Gaussian setting
Rebecca E. Morrison, Ricardo Baptista, Youssef Marzouk
We present an algorithm to identify sparse dependence structure in continuous and non-Gaussian probability distributions, given a corresponding set of data. The conditional indepen…
