Information theory for fields

TA Enßlin - Annalen der Physik, 2019 - Wiley Online Library
A physical field has an infinite number of degrees of freedom since it has a field value at
each location of a continuous space. Therefore, it is impossible to know a field from finite …

Variational inference for stochastic differential equations

M Opper - Annalen der Physik, 2019 - Wiley Online Library
The statistical inference of the state variable and the drift function of stochastic differential
equations (SDE) from sparsely sampled observations are discussed herein. A variational …

Marginal process framework: A model reduction tool for Markov jump processes

L Bronstein, H Koeppl - Physical Review E, 2018 - APS
Markov jump process models have many applications across science. Often these models
are defined on a state space of product form and only one of the components of the process …

Sparse Kernel Gaussian Processes through Iterative Charted Refinement (ICR)

G Edenhofer, RH Leike, P Frank, TA Enßlin - arXiv preprint arXiv …, 2022 - arxiv.org
Gaussian Processes (GPs) are highly expressive, probabilistic models. A major limitation is
their computational complexity. Naively, exact GP inference requires $\mathcal {O}(N^ 3) …

Geometric variational inference and its application to bayesian imaging
