Researchers have developed new Krylov subspace-based methods to significantly speed up computations for generalized mixed-effects models, particularly those with high-dimensional crossed random effects. These new methods offer speedups of several orders of magnitude and improved computational robustness compared to traditional Cholesky decomposition techniques. The proposed methods maintain essentially the same accuracy as existing approaches and are analyzed both theoretically and empirically, with applications to simulated and real-world data. AI
IMPACT These computational advancements could enable more efficient analysis of complex datasets in AI and machine learning research.
