Easing Color Shifts in Score-Based Diffusion Models
Katherine Deck, Tobias Bischoff
Generated images of score-based models can suffer from errors in their spatial means, an effect, referred to as a color shift, which grows for larger images. This paper investigate…
Unpaired Downscaling of Fluid Flows with Diffusion Bridges
Tobias Bischoff, Katherine Deck
We present a method to downscale idealized geophysical fluid simulations using generative models based on diffusion maps. By analyzing the Fourier spectra of images drawn from diff…
Unsupervised Discovery of El Nino Using Causal Feature Learning on Microlevel Climate Data
Krzysztof Chalupka, Tobias Bischoff, Pietro Perona +1
We show that the climate phenomena of El Nino and La Nina arise naturally as states of macro-variables when our recent causal feature learning framework (Chalupka 2015, Chalupka 20…
The stability of stratified spatially periodic shear flows at low Péclet number
Pascale Garaud, Basile Gallet, Tobias Bischoff
This work addresses the question of the stability of stratified, spatially periodic shear flows at low Péclet number but high Reynolds number. This little-studied limit is motivate…
Order-disorder transitions in a sheared many body system
Jens C. Pfeifer, Tobias Bischoff, Georg Ehlers +1
Motivated by experiments on sheared suspensions that show a transition between ordered and disordered phases, we here study the long-time behavior of a sheared and overdamped 2-d s…
