Self-certifying classification by linearized deep assignment

B Boll, A Zeilmann, S Petra, C Schnörr - arXiv preprint arXiv:2201.11162, 2022 - arxiv.org
We propose a novel class of deep stochastic predictors for classifying metric data on graphs
within the PAC-Bayes risk certification paradigm. Classifiers are realized as linearly …

A Nonlocal Graph-PDE and Higher-Order Geometric Integration for Image Labeling

D Sitenko, B Boll, C Schnörr - SIAM Journal on Imaging Sciences, 2023 - SIAM
This paper introduces a novel nonlocal partial difference equation (G-PDE) for labeling
metric data on graphs. The G-PDE is derived as a nonlocal reparametrization of the …

Nonlocal Graph-PDEs and Riemannian Gradient Flows for Image Labeling

D Sitenko - 2023 - archiv.ub.uni-heidelberg.de
In this thesis, we focus on the image labeling problem which is the task of performing unique
pixel-wise label decisions to simplify the image while reducing its redundant information. We …
