ADVENT: Adversarial Entropy Minimization for Domain Adaptation in Semantic Segmentation

Computer Vision and Pattern Recognition, 2018
Semantic segmentation is a key problem for many computer vision tasks. While approaches based on convolutional neural networks constantly break new records on different benchmarks, generalizing well to diverse testing environments remains a major ...

Entropy

2008
This article presents a scientific overview of ‘entropy’ as a thermodynamic basic function. A primary definition of entropy is stated in classical thermodynamics and statistical mechanics. The second law of thermodynamics states that, in any physical or chemical process, the quality of the energy in a system degrades, thus proving the existence of ...

When is an Entropy an Entropy?

AIP Conference Proceedings, 2006
I consider the conceptual arguments leading to the validity of the conventional physical approach to thermodynamics, as we know it. In spite of the familiarity we have with this approach, its internal logical structure deserves to be extracted. No new features are found, but some universal properties emerge. These are then applied to the unconventional

Entropy

Best Practice & Research Clinical Anaesthesiology, 2006
The concept of entropy, originally derived from thermodynamics, has been successfully applied to EEG analysis. Various entropy algorithms have been used in clinical studies, but until now a commercially available monitor exists only for spectral entropy.

Entropie S * (entropy S *)

2000
Es handelt sich um eine extensive Zustandsgrose eines Systems im thermodynamischen Gleichgewicht, die eine zentrale Grose der Thermodynamik darstellt. Als Zustandsgrose besitzt S * ein vollstandiges Differential. Die Definition der Entropie erfolgt uber den zweiten Hauptsatz der Thermodynamik.

Entropy and Entropy Production

1973
The limitations of a thermodynamic theory of a continuum by the atomic structure of matter are briefly discussed. They imply that any thermodynamic theory is of an approximate nature. Main emphasis is laid on the concept of a nonequilibrium entropy. It is shown that to an isothermal electrical network one can apply thermodynamic reasoning.

Entropy and the Entropy Principle

2019
Clausius generalized the mathematical expression of Carnot’s principle obtained by Kelvin, and in 1865, introduced the concept of entropy and formulated the entropy principle. With the concept of entropy and the idea of the entropy principle, a definition of heat can be given, as well as mathematical formalism on equilibrium thermodynamics was ...
