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

Presents a novel method for tuning the regularization hyper-parameter, λ, of a ridge regression that is faster to compute than leave-one-out cross-validation (LOOCV) while yielding estimates of the regression parameters of equal, or particularly in the setting of sparse covariates, superior quality to those obtained by minimising the LOOCV risk

An Introduction to Subgroup Discovery

Published:

Subgroup discovery (SGD) is a form of local pattern discovery for labeled data that can help find interpretable descriptors from materials-science data obtained by first-principles calculations. In contrast to global modeling algorithms like kernel ridge regression or artificial neural networks, SGD finds local regions in the input space in which a target property takes on an interesting distribution. These local distributions can potentially reflect interesting scientific phenomena that are not represented in standard machine learning models. In this talk, we go over the conceptual basics of SGD, sketch corresponding search algorithms, and show some exemplary applications to materials-science data obtained by first-principles calculations.
