Bootstrap Methods for High-Dimensional and Large-Scale Data

Miles Lopes University of California, Davis

Bootstrap methods are among the most broadly applicable tools for statistical inference and uncertainty quantification. Although these methods have an extensive literature, much remains to be understood about their applicability in modern settings, where observations are high-dimensional, or where the quantity of data outstrips computational resources. In this talk, I will present a couple of new bootstrap methods that are tailored to these settings. First, I will discuss the topic of "spectral statistics" arising from high-dimensional sample covariance matrices, and describe a method for approximating the laws of such statistics. Second, in the context of large-scale data, I will discuss a more unconventional application of the bootstrap -- dealing with the tradeoff between accuracy and computational cost for ensemble classifiers. More specifically, I will explain how the bootstrap can be used to decide when an ensemble of classifiers trained by bagging or random forests is sufficiently large. This will include joint work with Alexander Aue and Andrew Blandino.
