Abstract:
In various decision making problems, one is given the advice or predictions of several classifiers of unknown reliability, over multiple questions or queries. This scenario is different from the standard supervised setting where classifier accuracy can be assessed using available labeled training or validation data, and raises several questions: given only the predictions of several classifiers...

Abstract:
We study a variant of the voter model on a dynamically changing network where agents have the option of changing their friends rather than changing their opinions. We analyse, in the context of dense random graphs, two models considered in Durrett et. al. (Proc. Natl. Acad. Sci. 109: 3682-3687, 2012). When an edge between two agents holding different opinions is updated, with...

Abstract:
Convex hull peeling, also called peeling the onion, refers to sorting points in Euclidean space into layers by repeatedly peeling off the vertices of the convex hull. It is widely used in robust statistics for ordering multi-variate data and defining a multi-variate median. Although much is known about the distributional properties of the points on the first convex layer, little is known about...

Statistics at UC Berkeley: We are a community engaged in research and education in probability and statistics. In addition to developing fundamental theory and methodology, we are actively involved in statistical problems that arise in such diverse fields as molecular biology, geophysics, astronomy, AIDS research, neurophysiology, sociology, political science, education, demography, and the U.S. Census. We have forged strong interdisciplinary links with other departments and areas of study, particularly biostatistics, mathematics, computer science, and biology, and actively seek to recruit graduate students and faculty who can help to build and maintain such links. We also offer a statistical consulting service each semester.
