The boundedness-by-entropy method for cross-diffusion systems
The global-in-time existence of bounded weak solutions to a large class of physically relevant, strongly coupled parabolic systems exhibiting a formal gradient-flow structure is proved. The main feature of these systems is that the diffusion matrix may be generally neither symmetric nor positive semidefinite. The key idea is to employ a transformation of variables, determined by the entropy den...
متن کاملThe Cross-Entropy Method
This report is a summary of the theory underlying the Cross-Entropy (CE) method, as discussed in the tutorial by de Boer, Kroese, Mannor and Rubinstein [1]. For a more thorough discussion of the method and its applications, please refer to the original tutorial and the references cited in the tutorial. The CE method, pioneered by Rubinstein in 1997 as an adaptive algorithm for estimating probab...
متن کاملEntropy, Duality, and Cross Diffusion
This paper is devoted to the use of the entropy and duality methods for the existence theory of reaction-cross diffusion systems consisting of two equations, in any dimension of space. Those systems appear in population dynamics when the diffusion rates of individuals of two species depend on the concentration of individuals of the same species (self diffusion), or of the other species (cross d...
متن کاملThe Cross-Entropy Method for Estimation
This chapter describes how difficult statistical estimation problems can often be solved efficiently by means of the cross-entropy (CE) method. The CE method can be viewed as an adaptive importance sampling procedure that uses the cross-entropy or Kullback–Leibler divergence as a measure of closeness between two sampling distributions. The CE method is particularly useful for the estimation of ...
متن کاملThe Cross-Entropy Method Optimizes for Quantiles
Cross-entropy optimization (CE) has proven to be a powerful tool for search in control environments. In the basic scheme, a distribution over proposed solutions is repeatedly adapted by evaluating a sample of solutions and refocusing the distribution on a percentage of those with the highest scores. We show that, in the kind of noisy evaluation environments that are common in decisionmaking dom...
