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. WebThe horseshoe prior has proven to be a noteworthy alternative for sparse Bayesian estimation, but as shown in this paper, the results can be sensitive to the prior choice for the global shrinkage hyperparameter.
