  • When do Random Forests work?

    When do Random Forests work? arXiv:2504.12860v1 Announce Type: new Abstract: We study the effectiveness of randomizing split-directions in random forests. Prior literature has shown that, on the one hand, randomization can reduce variance through decorrelation, and, on the other hand, randomization regularizes and works in low signal-to-noise ratio (SNR) environments. First, we bring together and…

  • Estimating shared subspace with AJIVE: the power and limitation of multiple data matrices

    Estimating shared subspace with AJIVE: the power and limitation of multiple data matrices arXiv:2501.09336v1 Announce Type: new Abstract: Integrative data analysis often requires disentangling joint and individual variations across multiple datasets, a challenge commonly addressed by the Joint and Individual Variation Explained (JIVE) model. While numerous methods have been developed to estimate the shared subspace…
