14) Nevertheless, it is important to note how this utopic tension also stems from the cybernetic concept of information as a force opposing universal chaos: in a scientific context, this is called negentropy.
Better still, it transforms an arguably closed-ended model into a model for negentropy.
At the same period, in 1950s, entropy and negentropy concepts which are inspired from thermodynamics and biology fields became important and needed to be considered.
Negentropy (reason / orderly energy or processes) calls forth unmistakeably the rise of entropy (emotion / disorderly energy or processes).
i] are maximally independent, measured by some statistics or functions ([10]), such as kurtosis, negentropy, and non-Gaussianity.
For sources with more negentropy property (non-Gaussian), the ICA generates component maps with higher discrimination of the source signal [26, 27].
The fastICA algorithm can exploit different nonlinear functions to approximate negentropy whose maximization leads to non-Gaussianity maximization.
14] first divided the cost function of ICA-R into two parts that are the negentropy function and the closeness measure function and then directly used the first-order derivative of the negentropy contrast function to update the separating vector.
To take an example, Schrodinger famously posited that negentropy was the basis of life.
It generates, like negentropy, a structure that constantly builds itself up against the flow of stable meanings.
Non-Gaussianity is the key to estimating the ICA model and can be measured by kurtosis, negentropy, and approximations of negentropy (Hyvarinen, Oja 2000).
