Envibayes2023

This is a recap of the Envibayes Workshop on Complex Environmental Data.

The purpose of this recap is to consolidate notes, with a focus on ideas I think might have potential for personal research pursuits.

The recap is ordered by talk, though some notes are only tangentially related to the talk under which they appear.

Veronica Berrocal Stationarity or non-stationarity: that is the question

• Mark Risser’s work, especially on non-stationary GP kernals for massive datasets

• four broad methods of nonstationary GP’s
