## Special Issue Information

Dear Colleagues,

The mathematical field of Information Geometry originated from the observation by C.R. Rao in 1945 that the Fisher information can be used to define a Riemannian metric in spaces of probability distributions. This led to a geometrical description of probability theory and statistics, allowing the study of the invariant properties of statistical manifolds. It was through the works of S.-I. Amari and others, that it was later realized that the differential-geometric structure of a statistical manifold can be derived from divergence functions, yielding a Riemannian metric and a pair of dually coupled affine connections.

Since then, Information Geometry has become a truly interdisciplinary field with applications in various domains. It enables a deeper understanding of the methods of statistical inference and machine learning, while providing a powerful framework for deriving new algorithms as well. As such, Information Geometry has many applications in optimization (e.g. on matrix manifolds), signal and image processing, computer vision, neural networks and other subfields of the information sciences. Furthermore, the methods of Information Geometry have been applied to a wide variety of topics in physics, mathematical finance, biology and the neurosciences. In physics, there are many links through the fields of (nonextensive) statistical mechanics and quantum mechanics, since these are also based on probability theory. In addition, there are recent indications that the formalism of Information Geometry may be suitable for explaining or deriving other physical laws as well.

For this special issue we welcome submissions related to the foundations and applications of Information Geometry. We envisage contributions that aim at clarifying the connection of Information Geometry with both the information sciences and the physical sciences, so as to demonstrate the profound impact of the field in these disciplines. In addition, we hope to receive original papers illustrating the wide variety of applications of the methods of Information Geometry.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. *Entropy* is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1500 CHF (Swiss Francs).
