Alternating minimization algorithm with initialization analysis for r-local and k-sparse unlabeled sensing
Ahmed Abbasi, Shuchin Aeron, Abiy Tasissa
Unlabeled sensing is a linear inverse problem with permuted measurements. We propose an alternating minimization (AltMin) algorithm with a suitable initialization for two widely co…
Nonparametric and Regularized Dynamical Wasserstein Barycenters for Sequential Observations
Kevin C. Cheng, Shuchin Aeron, Michael C. Hughes +1
We consider probabilistic models for sequential observations which exhibit gradual transitions among a finite number of states. We are particularly motivated by applications such a…
Measure Estimation in the Barycentric Coding Model
Matthew Werenski, Ruijie Jiang, Abiy Tasissa +2
This paper considers the problem of measure estimation under the barycentric coding model (BCM), in which an unknown measure is assumed to belong to the set of Wasserstein-2 baryce…
