Efficient Sparse Bayesian Learning using Spike-and-Slab Priors
WebJan 1, 2024 · However, the spike-and-slab lasso, and most of the previous methods, were developed based on normal linear models, and cannot be directly applied to other models. Therefore, extensions of high-dimensional methods using mixture priors to frameworks beyond normal linear regression provide important new research directions for both … WebSpike-and-Slab LASSO is a spike-and-slab refinement of the LASSO procedure, using a mixture of Laplace priors indexed by lambda0 (spike) and lambda1 (slab). The SSLASSO procedure fits coefficients paths for Spike-and-Slab LASSO-penalized linear regression models over a grid of values for the regularization parameter lambda0. parka longue pour femme

WebFor this task, we propose a new biclustering method called Spike-and-Slab Lasso Biclustering (SSLB). SSLB utilizes the SSL prior to find a doubly-sparse factorization of the data matrix via a fast EM algorithm. Applied to both a microarray dataset and a single-cell RNA-sequencing dataset, SSLB recovers biologically meaningful signal in the data. WebMar 1, 2024 · Recently, there has been a rapid development in spikeand-slab lasso (SSL) methods to solve various high-dimensional problems, including (generalized) linear … Webpopular spike and slab prior with Laplace slabs in high-dimensional logistic regression.
