%description
Deep compositional spatial models are standard spatial covariance models
coupled with an injective warping function of the spatial domain. The
warping function is constructed through a composition of multiple
elemental injective functions in a deep-learning framework. The package
implements two cases for the univariate setting; first, when these warping
functions are known up to some weights that need to be estimated, and,
second, when the weights in each layer are random. In the multivariate
setting only the former case is available. Estimation and inference is
done using 'tensorflow', which makes use of graphics processing units. For
more details see Zammit-Mangion et al. (2022)
