The old cedar in Southend's Chalkwell Park had been standing for 350 years when, in 1919, a photographer snapped children sitting on the iron bench which encircled it.

Gaussian random fields (GRFs) play an important part in spatial modelling, but can be computationally infeasible for general covariance structures. An efficient approach is to specify GRFs via ...

The main novelty of our random tree model of memory and recall is the assumption that any meaningful material is generically represented in the same fashion.
