Bayesian Tracking of a Diffusing Target in Two and Three Dimensions
Ewan McCulloch, Adam Nahum
We study Bayesian tracking of a diffusing target monitored by a noisy distributed sensor array. Building on an earlier mapping to KPZ growth with a moving defect (or an equivalent…

Bayesian phase transition for the critical Ising model: Enlarged replica symmetry in the epsilon expansion and in 2D
Kay Joerg Wiese, Alapan Das, Adam Nahum
A process that images or measures bond energies in the critical Ising model can be in distinct measurement ``phases'', depending on the precision of measurement. We study the trans…

Bayesian critical points in classical lattice models
Adam Nahum, Jesper Lykke Jacobsen
The Boltzmann distribution encodes our subjective knowledge of the configuration in a classical lattice model, given only its Hamiltonian. If we acquire further information about t…
