Relative Entropy in Biological Systems
Entropy, 2016 In this paper we review various information-theoretic characterizations of the approach to equilibrium in biological systems. The replicator equation, evolutionary game theory, Markov processes and chemical reaction networks all describe the dynamics of ...

Entanglement entropy, relative entropy and duality
Journal of High Energy Physics, 2019 A definition for the entanglement entropy in both Abelian and non-Abelian gauge theories has been given in the literature, based on an extended Hilbert space construction.

Journal of High Energy Physics, 2018 One characteristic feature of a chaotic system is the quick delocalization of quantum information (fast scrambling). One therefore expects that in such a system a state quickly becomes locally indistinguishable from its perturbations.

Relative Entropy Derivative Bounds
Entropy, 2013 We show that the derivative of the relative entropy with respect to its parameters is lower and upper bounded. We characterize the conditions under which this derivative can reach zero.

Parametric Bayesian Estimation of Differential Entropy and Relative Entropy
Entropy, 2010 Given iid samples drawn from a distribution with known parametric form, we propose the minimization of expected Bregman divergence to form Bayesian estimates of differential entropy and relative entropy, and derive such estimators for the uniform ...

Relative cluster entropy for power-law correlated sequences
SciPost Physics, 2022 We propose an information-theoretical measure, the \textit{relative cluster entropy} $\mathcal{D_{C}}[P \| Q] $, to discriminate among cluster partitions characterised by probability distribution functions $P$ and $Q$.

The improved relative entropy for face recognition
MATEC Web of Conferences, 2016 The relative entropy is least sensitive to noise. In this paper, we propose the improved relative entropy for face recognition (IRE). The IRE method of recognition rate is far higher than the LDA, LPP method, by experimental results on CMU PIE face ...

A Novel Distance Metric: Generalized Relative Entropy
Entropy, 2017 Information entropy and its extension, which are important generalizations of entropy, are currently applied to many research domains. In this paper, a novel generalized relative entropy is constructed to avoid some defects of traditional relative ...

Meta-inverse Reinforcement Learning Method Based on Relative Entropy [PDF]
Jisuanji kexue, 2021 Aiming at the problem that traditional inverse reinforcement learning algorithms are slow,imprecise,or even unsolvable when solving the reward function owing to insufficient expert demonstration samples and unknown state transition probabilitie,a meta ...

Relative model of the logical entropy of sub-$\sigma_\Theta$-algebras [PDF]
Journal of Mahani Mathematical Research, 2023 In the context of observers, any mathematical model according to the viewpoint of an observer $ \Theta $ is called a relative model. The purpose of the present paper is to study the relative model of logical entropy. Given an observer $ \Theta $,
