Splet06. jun. 2024 · Shrinkage: Shrinkage is commonly used in ridge regression where it shrinks regression coefficients to zero and, thus, reduces the impact of potentially unstable regression coefficients. In GBM’s, shrinkage is used for reducing the impact of each additionally fitted base-learner. Splet28. sep. 2024 · In this paper, we present a novel shrinkage estimator for data residing in Lie groups, specifically, abelian or compact Lie groups. The key theoretical results presented in this paper are: (i) Stein's Lemma and its proof for Lie groups and, (ii) proof of dominance of the proposed shrinkage estimator over MLE for abelian and compact Lie groups.

The graph y=k⋅f(x) (where k is a real number) is similar to the graph y=f(x), but each point's distance from the x-axis is multiplied by k. A similar thing happens when we graph y=f(k⋅x), only now the distance from the y-axis changes.
