SV: [Fis] Re: What is the definition of information ?

I support that. If Pedro would collect them on the FIS website it would be great. The discussion can then first center on getting the various definitions right. Then we can discuss what they encompass and where they are useful.

Listing the currently accepted definitions of information would
be nice. The list should at least include the ones used in
math/computer science: Fisher information, Shannon/Renyi information
(which is quite different from the Fisher information), etc...:
e.g. look to the Wikipedia site.
But information concepts are needed in other areas and
all definitions may be criticized since none of them is
suitable in all areas.
