Adaptive Random Matrices in Gaussian Bandits: Spectral Universality and Selection-Induced Outliers

Adaptive arm selection changes the distribution of the observations collected by a bandit algorithm, but it need not change their limiting empirical spectrum. We study Gaussian bandit designs in which the dimension and the number of observations grow proportionally. A quantitative coupling theorem compares the design g...

Cluster-Based Dimensionality Reduction by Nonparametric Distributional Screening

The objective is not to construct a low-rank projection, but to retain an interpretable subset of the original coordinates that preserves the distributional information distinguishing the clusters that preserves the distributional information distinguishing the clusters.
