Complex ICA by Negentropy Maximization
IEEE Transactions on Neural Networks, 2008In this paper, we use complex analytic functions to achieve independent component analysis (ICA) by maximization of non-Gaussianity and introduce the complex maximization of non-Gaussianity (CMN) algorithm. We derive both a gradient-descent and a quasi-Newton algorithm that use the full second-order statistics providing superior performance with ...

WOOLHOUSE1 remarks that the work of Shannon and Brillouin showed the fundamental relationship between information defined as I=−ΣPi log Pi (where 0 ⩽Pi⩽1, ΣPi=1 and Pi is the relative probability of the ith symbol generated by a source), and entropy defined in statistical terms as S=−KΣPi log Pi (where ΣPi=1 and Pi is, in this case, the probability of ...

Teleology can be defined as goal seeking behaviour with production of negentropy, i.e. with generation of an state improbable under the given conditions. Contrary to an opinion often hold, the production of negentropy does not mean an decrease of entropy.

Generalized Negentropy for Statistical Dependence
2007 International Conference on Information Acquisition, 2007In this paper, we propose a generalized form of negentropy using the density power divergence, which can compromise between robustness and effectiveness. The conventional form of negentropy can be considered as its special case. From the fact that statistical dependence measures such as the mutual information can be defined in terms of joint and ...

On information, negentropy andH-theorem
Zeitschrift f�r Physik B Condensed Matter, 1983The paper deals with the imprtance of the Kullback descrimination information in the statistical characterization of negentropy of non-equilibrium state and the irreversibility of a classical dynamical system. The theory based on the Kullback discrimination information as theH-function gives new insight into the interrelation between the concepts of ...

Negentropy in microdrops of water
Physics Letters A, 1989The negative sign of dP/dT which arises in microdrops of water was examined and it became clear that the microdrop has negative entropy (negentropy) for the increase in volume and that the microdrop can be a satisfactory engine for the biological cell.

Entropy and negentropy (Edtl.)
IRE Transactions on Information Theory, 1957Certainly there is a relationship between the mathematical theory of communication and statistical thermodynamics. It should be made clear without any doubt or hesitation that the term entropy is used in information theory by mathematical analogy. The expression X, which we call the entropy of a set of probabilities, is identical in form and in sign ...

Information, Regulation, Negentropy
1982It might seem that the question about the meaning of the word ‘information’ should be addressed to the representatives of information theory, a discipline so very popular today. As a matter of fact, however, information theory is not concerned with this question, or else has only a very marginal interest in it.

On information, negentropy and thermostatistics
Pramana, 1983The interrelation between some basic concepts of information, theory and thermodynamics has been studied on the basis of the statistical measures of entropy and information. The problems studied are the negentropy principle of information, a minimax information principle of thermal equilibrium and the role of information correlation in the derivation ...
