Joint Model and Data Sparsification via the Marginal Likelihood
A new approach to Sparse Bayesian Learning has been proposed, focusing on joint model and data sparsification through marginal likelihood optimization. This method aims to enhance feature sparsity while addressing the limitations of traditional homoscedastic noise models, which are sensitive to data contamination. The proposed technique allows for simultaneous learning of feature and sample relevancies, improving model fit and predictions across various regression tasks.
