| Optimally Weighted PCA for High-Dimensional Heteroscedastic Data | Robust and High-Dimensional Statistics (Simons Institute workshop, 2018) | 2018-10-29 |
Asymptotic analysis shows column-weighted PCA recovers a low-rank subspace better than unweighted PCA under heteroscedastic noise: with n,d → ∞ at fixed ratio… | ||
| Subspace Clustering using Ensembles of K-Subspaces | Randomized Numerical Linear Algebra and Applications 2018 | 2018-09-24 |
K-subspaces is NP-hard in worst case, so the practical method draws many random K-subspaces initializations, builds an averaged co-association matrix… | ||
