Super-Resolution Radar
Reinhard Heckel, Veniamin I. Morgenshtern, Mahdi Soltanolkotabi
In this paper we study the identification of a time-varying linear system from its response to a known input signal. More specifically, we consider systems whose response to the in…
Subspace clustering of dimensionality-reduced data
Reinhard Heckel, Michael Tschannen, Helmut Bölcskei
Subspace clustering refers to the problem of clustering unlabeled high-dimensional data points into a union of low-dimensional linear subspaces, assumed unknown. In practice one ma…
Neighborhood Selection for Thresholding-based Subspace Clustering
Reinhard Heckel, Eirikur Agustsson, Helmut Bölcskei
Subspace clustering refers to the problem of clustering high-dimensional data points into a union of low-dimensional linear subspaces, where the number of subspaces, their dimensio…
