Regression on Ice: Function approximation for the mathematically-inclined glaciologist
17 Sep 2023 | Contributor(s):: Noah J Bergam
Modern satellite-based analysis of the ice sheets presents a profound statistical-geometric problem: how do we make sense of scattered, noisy measurements of vast, steadily evolving surfaces like the Greenland and Antarctic ice sheets? In these lecture notes, I attempt to provide the...
