Dreaming More Data: Class-dependent Distributions over Diffeomorphisms for Learned Data Augmentation
Søren Hauberg, Oren Freifeld, Anders Boesen Lindbo Larsen +2
Data augmentation is a key element in training high-dimensional models. In this approach, one synthesizes new observations by applying pre-specified transformations to the original…
Bayesian inference for spatio-temporal spike-and-slab priors
Michael Riis Andersen, Aki Vehtari, Ole Winther +1
In this work, we address the problem of solving a series of underdetermined linear inverse problems subject to a sparsity constraint. We generalize the spike-and-slab prior distrib…
Spatio-temporal Spike and Slab Priors for Multiple Measurement Vector Problems
Michael Riis Andersen, Ole Winther, Lars Kai Hansen
We are interested in solving the multiple measurement vector (MMV) problem for instances, where the underlying sparsity pattern exhibit spatio-temporal structure motivated by the e…
