Continuous shrinkage prior
WebOct 14, 2024 · While enjoying its efficiency in posterior simulations, the shrinkage prior can lead to a nearly optimal posterior contraction rate and the variable selection consistency as the spike-and-slab prior. WebWe propose a new class of priors for linear regression, the R-square induced Dirichlet Decomposition (R2-D2) prior. The prior is induced by a Beta prior on the coefficient of determination, and then the total prior variance of the regression coefficients is decomposed through a Dirichlet prior. We demonstrate both theoretically and empirically the …

WebFor the shrinkage prior, there is only a single model used in posterior simulations, and thus some gradient-based MCMC algorithms, such as stochastic gradient Langevin dynamics (SGLD) [68], Hamiltonian Monte Carlo [18,47], Riemann manifold Hamiltonian Monte Carlo [28], and stochastic gradient Hamiltonian Monte Carlo [15], can be easily used in … Webshrinkage pro le expects to see two things a priori: strong signals ( ˇ0, no shrinkage), and zeros ( ˇ1, total shrinkage). No other commonly used shrinkage prior shares these …

WebThe hierarhical shrinkpage plus ( hs_plus) prior is similar except that the standard deviation that is distributed as the product of two independent half Cauchy parameters that are each scaled in a similar way to the hs prior. The hierarchical shrinkage priors have very tall modes and very fat tails. WebMar 17, 2024 · In this paper, we focus on the class of global-local shrinkage priors , and more specifically the horseshoe prior, which has been recognised as a good default prior choice for Bayesian sparse estimation [3, 7]. The horseshoe prior has a pole at \(\beta _j = 0\), and heavy, Cauchy-like tails. These properties are desirable in sparse estimation ...
WebThe first class, spike-and-slab prior, places a discrete mixture of a point mass at zero (the spike) and an ab-solutely continuous density (the slab) on each param-eter. The second entails placing absolutely continuous shrinkage priors on the entire parameter vector that se-lectively shrinks the small signals. Table 2 provides a
