Diffusion differentiable resampling
Jennifer Rosina Andersson, Zheng Zhao
This paper is concerned with differentiable resampling in the context of sequential Monte Carlo (e.g., particle filtering). Drawing on reparametrisation, we propose a new resamplin…

Probabilistic Zeeman-Doppler imaging of stellar magnetic fields: I. Analysis of tau Scorpii in the weak-field limit
Jennifer Rosina Andersson, Oleg Kochukhov, Zheng Zhao +1
Zeeman-Doppler imaging (ZDI) is used to study the surface magnetic field topology of stars, based on high-resolution spectropolarimetric time series observations. Multiple ZDI inve…

Ising on the Graph: Task-specific Graph Subsampling via the Ising Model
Maria BÃ¥nkestad, Jennifer R. Andersson, Sebastian Mair +1
Reducing a graph while preserving its overall properties is an important problem with many applications. Typically, reduction approaches either remove edges (sparsification) or mer…
