Relations between Renyi Distance and Fisher Information
In this paper, we first show that Renyi distance between any member of a parametric family and its perturbations, is proportional to its Fisher information. We, then, prove some relations between the Renyi distance of two distributions and the Fisher information of their exponentially twisted family of densities. Finally, we show that the partial ordering of families induced by Renyi dis...
متن کاملComment on “ Spacetime Information ”
A recent paper by Hartle [1] proposes a definition of “spacetime information” — the information available about a quantum system’s boundary conditions in the various sets of decohering histories it may display — and investigates its properties. We note here that the analysis of Ref. [1] contains errors which invalidate several of the conclusions. In particular, the proof that the proposed defin...
متن کاملInformation Distance - Information Theory, IEEE Transactions on
While Kolmogorov complexity is the accepted absolute measure of information content in an individual finite object, a similarly absolute notion is needed for the information distance between two individual objects, for example, two pictures. We give several natural definitions of a universal information metric, based on length of shortest programs for either ordinary computations or reversible ...
متن کاملInformation Technology and Distance Education
Advances in information technologies (IT) are one of the driving forces of change in Higher Education. As colleges and universities attempt to more aggressively pursue distance education as a means in search of increasing revenue, enrollment and visibility, they must identify the current and perspective students and their needs. There have been continuous research and debate on open source lear...
متن کاملInformation Distance and Its Extensions
Consider, in the most general sense, the space of all information carrying objects: a book, an article, a name, a definition, a genome, a letter, an image, an email, a webpage, a Google query, an answer, a movie, a music score, a Facebook blog, a short message, or even an abstract concept. Over the past 20 years, we have been developing a general theory of information distance in this space and...
