On Rank Energy Statistics via Optimal Transport: Continuity, Convergence, and Change Point Detection
Matthew Werenski, Shoaib Bin Masud, James M. Murphy +1
This paper considers the use of recently proposed optimal transport-based multivariate test statistics, namely rank energy and its variant the soft rank energy derived from entropi…
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…
Interpretable contrastive word mover's embedding
Ruijie Jiang, Julia Gouvea, Eric Miller +2
This paper shows that a popular approach to the supervised embedding of documents for classification, namely, contrastive Word Mover's Embedding, can be significantly enhanced by a…
r-local sensing: Improved algorithm and applications
Ahmed Ali Abbasi, Abiy Tasissa, Shuchin Aeron
The unlabeled sensing problem is to solve a noisy linear system of equations under unknown permutation of the measurements. We study a particular case of the problem where the perm…
