"Stochastic Inverse Problems" and Changes-of-Variables
Peter W. Marcy, Rebecca E. Morrison
Over the last decade, a series of applied mathematics papers have explored a type of inverse problem--called by a variety of names including "inverse sensitivity", "pushforward bas…
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…
Learning non-Gaussian graphical models via Hessian scores and triangular transport
Ricardo Baptista, Youssef Marzouk, Rebecca E. Morrison +1
Undirected probabilistic graphical models represent the conditional dependencies, or Markov properties, of a collection of random variables. Knowing the sparsity of such a graphica…
Embedded model discrepancy: A case study of Zika modeling
Rebecca E. Morrison, Americo Cunha
Mathematical models of epidemiological systems enable investigation of and predictions about potential disease outbreaks. However, commonly used models are often highly simplified…
Embedded discrepancy operators in reduced models of interacting species
Rebecca E Morrison
In many applications of interacting systems, we are only interested in the dynamic behavior of a subset of all possible active species. For example, this is true in combustion mode…
Exact Reduction of the Generalized Lotka-Volterra Equations via Integral and Algebraic Substitutions
Rebecca E. Morrison
Systems of interacting species, such as biological environments or chemical reactions, are often described mathematically by sets of coupled ordinary differential equations. While…
