WebDec 21, 2024 · The horseshoe prior has proven itself to be optimal in sparse signal recovery, and we are able to access the quality of this recovery thanks to the theories and methods developed in the paper. It would be interesting also to consider other classes of priors, e.g., spike-and-slab types, and I hope that there will be more papers on Bayesian ... WebFeb 28, 2016 · Horseshoe priors are similar to lasso and other regularization techniques, but have been found to have better performance in many situations. A regression coefficient β i, where i ∈ { 1, D } predictors, has a horseshoe prior if its standard deviation is the product of a local ( λ i) and global ( τ) scaling parameter.
