Preface
This edited book project entitled Progress in Information Geometry: Theory and
Applications (PIGTA) started in October 2019, right after the fourth biannual
conference on the Geometric Science of Information (GSI) which took place at the
end of August 2019 in Toulouse (France). The proceedings of the fourth GSI were
published by Springer in the LNCS series (volume 11712, https://www.springer.
com/gp/book/9783030269791). The international conference was a nice opportunity
to interact with colleagues willing to contribute to this book. In the past, let us
quickly mention that we carried out similar projects after conference/workshop
events as follows:
• The book “Matrix Information Geometry” was published in 2013 after holding the
Info-French workshop in 2011 on this theme (https://www.springer.com/gp/book/
9783642302312),
• The book “Geometric Theory of Information” was published in 2014 after the First
International Conference on Geometric Science of Information (GSI) held at École
des Mines (Paris, France) in August 2013.
• The book “Computational Information Geometry: For Image and Signal
Processing” was published in 2017 (https://www.springer.com/gp/book/978331
9470566) after the event held at the International Centre for Mathematical
Sciences (ICMS, Edinburgh, UK) in September 2015.
• The book “Geometric Structures of Information” was published (https://www.spr
inger.com/gp/book/9783030025199) in 2019 after the Third International
Conference on Geometric Science of Information (GSI) held at École des Mines
ParisTech (Paris, France) in November 2017.
This book project was originally called Advances in Information Geometry (AIG)
but we decided to rename it later to avoid confusion since the book title coincided
with another planned international event scheduled to be held in Japan in March 2020
(https://sites.google.com/view/aig2020/). However, the AIG conference event was
unfortunately canceled due to the worldwide spread of the coronavirus (COVID-19).
