All-pole centroids in the Wasserstein metric with applications to clustering of spectral densities
Rumeshika Pallewela, Filip Elvander
In this work, we propose a method for computing centroids, or barycenters, in the spectral Wasserstein-2 metric for sets of power spectral densities, where the barycenters are rest…

Room Impulse Response Estimation through Optimal Mass Transport Barycenters
Rumeshika Pallewela, Yuyang Liu, Filip Elvander
In this work, we consider the problem of jointly estimating a set of room impulse responses (RIRs) corresponding to closely spaced microphones. The accurate estimation of RIRs is c…
