Title: "Squeezing the most out of ridge" Speaker: Professor Mark van de Wiel, Amsterdam University Medical Center Abstract: Ridge regression is nowadays regarded as a somewhat old-fashioned technique: most statisticians prefer sparse models, while machine learners use non-linear, multi-layer prediction algorithms. The aim of this talk is to endorse ridge by illustrating its strengths, from a methodological, computational and applied perspective, including: Flexibility (in terms of output and type of covariates) Bayesian counterpart facilitates empirical Bayes estimation of penalty parameter(s)…

Speaker: Ingeborg Hem, Norwegian University of Science and Technology Title: "Including expert knowledge in genomic selection through intuitive tree-based joint priors" Abstract: Bayesian hierarchical models with additive latent structures are popular since additivity simplifies interpretation and inference. However, the common choice of independent priors on the variances of the model components result in haphazard a priori control on the total variance and how it is attributed to the model components. We propose a joint prior for the variance parameters that…
