There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu
*********************************
In the early 1950's Herbert Robbins (1915-2001)
introduced the
Gamma-Minimax or Bayes-Minimax Paradigm,
as a compromise between Minimax and Bayes
Paradigms. Gamma-Minimax actions rely on
Min-Max type theorems and are often hard or
impossible to find.
In this talk we overview linear approximations
to Gamma-minimax actions and demonstrate
that in many decision theoretic problems
linear approximations are not substantially affecting
the risk of the decision maker.
The talk is a mixture of educational and research overviews,
and does not assume prior exposure to minimaxity and
Gamma-minimaxity.
