We say that two free p.m.p. actions of countable groups are Shannon orbit equivalent if there is an equivalence between them whose associated cocycle partitions have finite entropy. show the acting sofic and each has a w-normal amenable subgroup which neither locally nor virtually cyclic then implies same maximum This extends result Austin beyond finitely generated setting consequence Bernoulli...

Abstract Hidden Markov chains are widely applied statistical models of stochastic processes, from fundamental physics and chemistry to finance, health, artificial intelligence. The hidden processes they generate notoriously complicated, however, even if the chain is finite state: no expression for their Shannon entropy rate exists, as set predictive features generically infinite. As such, date ...

Image segmentation plays an important role in medical imaging applications. Therefore, accurate methods are needed for the successful segmentation of medical images for diagnosis and detection of various diseases. In this paper, we have used maximum entropy to achieve image segmentation. Maximum entropy has been calculated using Shannon, Renyi and Tsallis entropies. This work has novelty based ...

We analyze a contrasting dynamical behavior of Gibbs–Shannon and conditional Kullback-Leibler entropies, induced by time-evolution of continuous probability distributions. The question of predominantly purposedependent entropy definition for non-equilibriummodel systems is addressed. The conditional Kullback–Leibler entropy is often believed to properly capture physical features of an asymptoti...

The introduction of the Rényi entropy allowed a generalization of the Shannon entropy and unified its notion with that of other entropies. However, so far there is no generally accepted conditional version of the Rényi entropy corresponding to the one of the Shannon entropy. Different definitions proposed so far in the literature lacked central and natural properties one way or another. In this...
