Normalizing flows on tori and spheres

DJ Rezende, G Papamakarios… - International …, 2020‏ - proceedings.mlr.press
Normalizing flows are a powerful tool for building expressive distributions in high
dimensions. So far, most of the literature has concentrated on learning flows on Euclidean …

Omnizoomer: Learning to move and zoom in on sphere at high-resolution

Z Cao, H Ai, YP Cao, Y Shan, X Qie… - Proceedings of the …, 2023‏ - openaccess.thecvf.com
Omnidirectional images (ODIs) have become increasingly popular, as their large field-of-
view (FoV) can offer viewers the chance to freely choose the view directions in immersive …

On synchronization in Kuramoto models on spheres

A Crnkić, V Jaćimović, M Marković - Analysis and Mathematical Physics, 2021‏ - Springer
We analyze two classes of Kuramoto models on spheres that have been introduced in
previous studies. Our analysis is restricted to ensembles of identical oscillators with the …

Viewing omnidirectional images (ODIs) in virtual reality (VR) represents a novel form of
media that provides immersive experiences for users to navigate and interact with digital …

ProPLIKS: Probablistic 3D human body pose estimation

K Shetty, A Birkhold, B Egger, S Jaganathan… - arxiv preprint arxiv …, 2024‏ - arxiv.org
We present a novel approach for 3D human pose estimation by employing probabilistic
modeling. This approach leverages the advantages of normalizing flows in non-Euclidean …

Poisson kernel-based clustering on the sphere: convergence properties, identifiability, and a method of sampling

M Golzy, M Markatou - Journal of Computational and Graphical …, 2020‏ - Taylor & Francis
Spherical or directional data arise in many applications of interest. Furthermore, many
nondirectional datasets can be usefully re-expressed in the form of directions and analyzed …

Response to glassy disorder in coin on spread of quantum walker

P Ghosh, K Sen, U Sen - arxiv preprint arxiv:2111.09827, 2021‏ - arxiv.org
We analyze the response to incorporation of glassy disorder in the coin operation of a
discrete-time quantum walk in one dimension. We find that the ballistic spread of the …

Protein Structure Parameterization via Mobius Distributions on the Torus

M Arashi, NN Rad, A Bekker, WD Schubert - arxiv preprint arxiv …, 2020‏ - arxiv.org
Proteins constitute a large group of macromolecules with a multitude of functions for all living
organisms. Proteins achieve this by adopting distinct three-dimensional structures encoded …
