Multilevel Particle Filters [PDF]
SIAM Journal on Numerical Analysis, 2017 In this paper the filtering of partially observed diffusions, with discrete-time observations, is considered. It is assumed that only biased approximations of the diffusion can be obtained, for choice of an accuracy parameter indexed by $l$. A multilevel estimator is proposed, consisting of a telescopic sum of increment estimators associated to the ...

Journal of Graph Algorithms and Applications, 2018 In this paper, we introduce and study multilevel planarity, a generalization of upward planarity and level planarity. Let $G = (V, E)$ be a directed graph and let $\ell: V \to \mathcal P(\mathbb Z)$ be a function that assigns a finite set of integers to each vertex.

Multilevel Societies in Birds [PDF]
Trends in Ecology & Evolution, 2021 There is growing interest in the study of multilevel societies, where social units comprising several individual animals (human and non-human) come together to form higher-level groupings. Grueter et al. [ 1 ] provided a useful definition of multilevel societies, highlighting that key characteristics of multilevel societies should include stability ...

Parallel Multilevel Preconditioners [PDF]
Mathematics of Computation, 1990 In this paper, we provide techniques for the development and analysis of parallel multilevel preconditioners for the discrete systems which arise in numerical approximation of symmetric elliptic boundary value problems. These preconditioners are defined as a sum of independent operators on a sequence of nested subspaces of the full approximation space.
