Fisher entropy
WebAug 18, 2016 · A dimension-free inequality is established that interpolates among entropy and Fisher information relations and suggests the possibility of an analogous reverse Brunn-Minkowski inequality and a related upper bound on surface area associated to Minkowski sums.

The relative entropy, or Kullback–Leibler divergence, between two distributions $${\displaystyle p}$$ and $${\displaystyle q}$$ can be written as $${\displaystyle KL(p:q)=\int p(x)\log {\frac {p(x)}{q(x)}}\,dx.}$$ Now, consider a family of probability … See more In mathematical statistics, the Fisher information (sometimes simply called information ) is a way of measuring the amount of information that an observable random variable X carries about an unknown … See more When there are N parameters, so that θ is an N × 1 vector The FIM is a N × N positive semidefinite matrix. … See more The Fisher information was discussed by several early statisticians, notably F.
