Discrete-Continuous ADMM for Transductive Inference in Higher-Order MRFs
This paper introduces a novel algorithm for transductive inference in
higher-order MRFs, where the unary energies are parameterized by a variable
classifier. The considered task is posed as a joint optimization problem in the
continuous classifier parameters and the discrete label variables. In contrast
to prior approaches such as convex relaxations, we propose an advantageous
decoupling of the objective function into discrete and continuous subproblems
and a novel, efficient optimization method related to ADMM. This approach
preserves integrality of the discrete label variables and guarantees global
convergence to a critical point. We demonstrate the advantages of our approach
in several experiments including video object segmentation on the DAVIS data
set and interactive image segmentation
Healthy living on a healthy planet - Summary
Unsere Lebensweise macht krank und zerstört die natürlichen Lebensgrundlagen. In der Vision „Gesund leben auf einer gesunden Erde“ werden menschliche Lebensbereiche – Ernähren, Bewegen, Wohnen – gesund und umweltverträglich gestaltet sowie planetare Risiken – Klimawandel, Biodiversitätsverlust, Verschmutzung – bewältigt. Gesundheitssysteme nutzen ihre transformativen Potenziale, Bildung und Wissenschaft befördern gesellschaftliche Veränderungen. Die Vision ist nur mit internationaler Kooperation realisierbar und erfordert eine globale Dringlichkeitsgovernance.Our lifestyle is making us ill and is destroying the natural life-support systems. In the vision of ‘healthy living on a healthy planet’, human spheres of life – what we eat, how we move, where we live – are designed to be both healthy and environmentally compatible, and planetary risks – climate change, biodiversity loss, pollution – have been overcome. Health systems harness their transformative potential; education and science promote societal change. The vision can only be realized with international cooperation and requires what the WBGU terms global urgency governance
