Acoustic Image Source Interpolation with Optimal Transport Barycenter
Yuyang Liu, Rumeshika Pallewela, Jesper Brunnström +2
Room impulse responses can be estimated via the image source model (ISM) using the image source point cloud (ISPC) of a physical source. However, because the source movement change…
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…
An Analysis of Minimum Error Entropy Loss Functions in Wireless Communications
Rumeshika Pallewela, Eslam Eldeeb, Hirley Alves
This paper introduces the minimum error entropy (MEE) criterion as an advanced information-theoretic loss function tailored for deep learning applications in wireless communication…
