A discrete Benamou-Brenier formulation of Optimal Transport on graphs
Kieran Morris, Oliver Johnson
We propose a discrete transport equation on graphs which connects distributions on both vertices and edges. We then derive a discrete analogue of the Benamou-Brenier formulation fo…
Johnson's contribution to the Discussion of `Statistical aspects of the Covid-19 response' by Wood et al
Oliver Johnson
This is a response to the paper "Some statistical aspects of the Covid-19 response" by Wood et al, submitted to the discussion at the read paper meeting of the Royal Statistical So…
The Double Emulator
Conor Crilly, Oliver Johnson, Alexander Lewis +1
Computer models (simulators) are vital tools for investigating physical processes. Despite their utility, the prohibitive run-time of simulators hinders their direct application fo…
Finite de Finetti bounds in relative entropy
Lampros Gavalakis, Oliver Johnson, Ioannis Kontoyiannis
We review old and recent finite de Finetti theorems in total variation distance and in relative entropy, and we highlight their connections with bounds on the difference between sa…
Relative entropy bounds for sampling with and without replacement
Oliver Johnson, Lampros Gavalakis, Ioannis Kontoyiannis
Sharp, nonasymptotic bounds are obtained for the relative entropy between the distributions of sampling with and without replacement from an urn with balls of colors. Our…
