RANSAC Algorithms for Subspace Recovery and Subspace Clustering
Ery Arias-Castro, Jue Wang
We consider the RANSAC algorithm in the context of subspace recovery and subspace clustering. We derive some theory and perform some numerical experiments. We also draw some corres…
Unconstrained and Curvature-Constrained Shortest-Path Distances and their Approximation
Ery Arias-Castro, Thibaut Le Gouic
We study shortest paths and their distances on a subset of a Euclidean space, and their approximation by their equivalents in a neighborhood graph defined on a sample from that sub…
Sequential Multiple Testing
Shiyun Chen, Ery Arias-Castro
We study an online multiple testing problem where the hypotheses arrive sequentially in a stream. The test statistics are independent and assumed to have the same distribution unde…
Semiparametric Estimation of Symmetric Mixture Models with Monotone and Log-Concave Densities
Xiao Pu, Ery Arias-Castro
In this article, we revisit the problem of fitting a mixture model under the assumption that the mixture components are symmetric and log-concave. To this end, we first study the n…
