Generalized Line Spectral Estimation via Convex Optimization
Reinhard Heckel, Mahdi Soltanolkotabi
Line spectral estimation is the problem of recovering the frequencies and amplitudes of a mixture of a few sinusoids from equispaced samples. However, in a variety of signal proces…
Active Ranking from Pairwise Comparisons and when Parametric Assumptions Don't Help
Reinhard Heckel, Nihar B. Shah, Kannan Ramchandran +1
We consider sequential or active ranking of a set of n items based on noisy pairwise comparisons. Items are ranked according to the probability that a given item beats a randomly c…
Super-Resolution MIMO Radar
Reinhard Heckel
A multiple input, multiple output (MIMO) radar emits probings signals with multiple transmit antennas and records the reflections from targets with multiple receive antennas. Estim…
Scalable and interpretable product recommendations via overlapping co-clustering
Reinhard Heckel, Michail Vlachos, Thomas Parnell +1
We consider the problem of generating interpretable recommendations by identifying overlapping co-clusters of clients and products, based only on positive or implicit feedback. Our…
