Covering point-sets with parallel hyperplanes and sparse signal recovery (Lenny Fukshansky, CMC)
Covering point-sets with parallel hyperplanes and sparse signal recovery (Lenny Fukshansky, CMC)
Let S be a set of k > n points in n-dimensional Euclidean space. How many parallel hyperplanes are needed to cover it? In fact, it is easy to prove that every such set can be covered by k-n+1 parallel hyperplanes, but do there exist sets that cannot be covered by fewer parallel hyperplanes? We […]

Title: Volumes and filling collections of multicurves Abstract: In this talk we will be concerned with links L in a Seifert-Fibered space N such that their projection to the base surface is a collection of curves G in minimal position. After stating a hyperbolization result, for the complement of L, in terms of G we […]
Kernel approaches in global statistical distances, local measure detection, and active learning
Kernel approaches in global statistical distances, local measure detection, and active learning
In this talk, we'll discuss the problem of constructing meaningful distances between probability distributions given only finite samples from each distribution. We approach this through the use of data-adaptive and localized kernels, and in a variety of contexts. First, we construct locally adaptive kernels to define fast pairwise distances between distributions, with applications to unsupervised […]
