A Comparative Framework for Preconditioned Lasso Algorithms

no code implementations NeurIPS 2013 Fabian L. Wauthier, Nebojsa Jojic, Michael. I. Jordan

The Lasso is a cornerstone of modern multivariate data analysis, yet its performance suffers in the common situation in which covariates are correlated.

Bayesian Bias Mitigation for Crowdsourcing

no code implementations NeurIPS 2011 Fabian L. Wauthier, Michael. I. Jordan

This approach can account for more complex bias patterns that arise in ambiguous or hard labeling tasks and allows us to merge data curation and learning into a single computation.
