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 ...

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 ...

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.

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.

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 ...

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 ...

The Negentropy Principle of Information
Journal of Applied Physics, 1953The statistical definition of information is compared with Boltzmann's formula for entropy. The immediate result is that information I corresponds to a negative term in the total entropy S of a system. S=S0−I. A generalized second principle states that S must always increase.

Negentropy-Oriented Society: Recoverability-Centered Social Architecture for the AI Era This paper proposes the concept of a Negentropy-Oriented Society as a framework for designing and evaluating social systems in the AI era. While contemporary AI governance and sustainability approaches emphasize optimization, efficiency, and risk mitigation, they ...

Negentropy and Information in Telecommunications, Writing, and Reading
Journal of Applied Physics, 1954The negentropy principle of information was discussed in a previous paper and applied to a variety of problems of scientific observation. The present paper considers the technical problems of telecommunication. Using a thermodynamical discussion one obtains the Shannon formula for the capacity of a channel with noise.
