Bayes beats cross validation: fast and accurate ridge regression via expectation maximization

Published in Proceedings of the 36th International Conference on Neural Information Processing Systems (NeurIPS), 2023

Ridge regression is one of the most widely used methods to fit linear regression models. Suprisingly, the established method for estimating its optimal shrinkage hyper-parameter value can be rather inaccurate. We show how a Bayesian formulation can address this issue.
