2018 Generalization of the de Bruijn Identity to General φ-Entropies and φ-Fisher Informations
abstract
In this paper, we propose generalizations of the de Bruijn identity based on extensions of the Shannon entropy, Fisher information and their associated divergences or relative measures. The foundations of these generalizations are the φ-entropies and divergences of the Csiszár (or Salicrú) class considered within a multidimensional context, including the one-dimensional case, and for several types of noisy channels characterized by a more general probability distribution beyond the well-known Gaussian noise. We found that the gradient and/or the Hessian of these entropies or divergences with respect to the noise parameter naturally give rise to generalized versions of the Fisher information or divergence, which are named the φ-Fisher information (divergence). The obtained identities can be viewed as further extensions of the classical de Bruijn identity. Analogously, it is shown that a similar relation holds between the φ-divergence and an extended mean-square error, named φ-mean square error, for the Gaussian channel.
