CiteSeerX — Handling sparsity via the horseshoe

WebThe advantages of the horseshoe are its robustness at handling unknown sparsity and large outlying signals. These properties are justified theoretically via a representation theorem and accompanied by comprehensive empirical experiments that compare its performance to benchmark alternatives. 1 WebThe so-called 'horseshoe' distribution is a Cauchy-Normal scale mixture, proposed as a sparsity-inducing prior for Bayesian regression. It is symmetric around zero, has heavy (Cauchy-like) tails, so that large coefficients face relatively little shrinkage, but an infinitely tall spike at 0, which pushes small coefficients towards zero. It is parameterized by a … WebApr 15, 2009 · The advantages of the horseshoe are its robustness at handling unknown sparsity and large outlying signals.
