نویسندگان
چکیده
We propose a method for testing homogeneity in three dimensional spatial distributions using Renyi entropy. apply the proposed to data from cosmological N-body simulations and Monte Carlo of homogeneous Poisson point process. show that can effectively characterize inhomogeneities identify any transition scale homogeneity, if present such distributions. The be used study cosmic future generation galaxy redshift surveys.

Selective ensemble of SVDDs with Renyi entropy based diversity measure
In this paper, a novel selective ensemble strategy for support vector data description (SVDD) using the Renyi entropy based diversity measure is proposed to deal with the problem of one-class classification. In order to obtain compact classification boundary, the radius of ensemble is defined as the inner product of the vector of combination weights and the vector of the radii of SVDDs. To make...
متن کاملA method for testing the cosmic homogeneity with Shannon entropy
We propose a method for testing Cosmic homogeneity based on the Shannon entropy in Information theory and test the potentials and limitations of the method on Monte Carlo simulations of some homogeneous and inhomogeneous 3D point process in a finite region of space. We analyze a set of N-body simulations to investigate the prospect of determining the scale of homogeneity with the proposed metho...
متن کاملRenyi Entropy Estimation Revisited
We revisit the problem of estimating entropy of discrete distributions from independent samples, studied recently by Acharya, Orlitsky, Suresh and Tyagi (SODA 2015), improving their upper and lower bounds on the necessary sample size n. For estimating Renyi entropy of order α, up to constant accuracy and error probability, we show the following Upper bounds n = O(1) · 2(1− 1 α )Hα for integer α...
متن کاملShannon Entropy , Renyi Entropy , and Information
This memo contains proofs that the Shannon entropy is the limiting case of both the Renyi entropy and the Tsallis entropy, or information. These results are also confirmed experimentally. We conclude with some general observations on the utility of entropy measures. A brief summary of the origins of the concept of physical entropy are provided in an appendix.
متن کاملA Comprehensive Comparison of Shannon Entropy and Smooth Renyi Entropy
We provide a new result that links two crucial entropy notions: Shannon Entropy H1 and collision entropy H2. Our formula gives the worst possible amount of collision entropy in a probability distribution, when its Shannon Entropy is fixed. Our results and techniques used in the proof immediately imply many quantitatively tight separations between Shannon and smooth Renyi entropy, which were pre...
