Weighted Frechet Means as Convex Combinations in Metric Spaces: Properties and Generalized Median Inequalities
Cedric E. Ginestet, Andrew Simmons, Eric D. Kolaczyk
In this short note, we study the properties of the weighted Frechet mean as a convex combination operator on an arbitrary metric space, (Y,d). We show that this binary operator is…
