International Conference on Artificial Intelligence and Statistics, Clearwater, 16-18 April … WebNov 29, 2016 · The horseshoe arises from the same class of multivariate scale mixtures of normals as the lasso does, but it is almost always superior to the double-exponential … 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 … 75%酒精消毒液和75%酒精一样吗
