CROWDMOS: An approach for crowdsourcing mean opinion score studies
MOS (mean opinion score) subjective quality studies are used to evaluate many signal processing methods. Since laboratory quality studies are time consuming and expensive, researc...

An acoustically-motivated spatial prior for under-determined reverberant source separation
We consider the task of under-determined reverberant audio source separation. We model the contribution of each source to all mixture channels in the time-frequency domain as a ze...

Data-driven fMRI group classification using connected components and Gaussian process classifiers
Functional magnetic resonance imaging (fMRI) is a popular tool for studying brain activity due to its non-invasiveness. Conventionally an expected response needs to be available f...

On the ergodic capacity of jointly-correlated rician Fading MIMO channels
—In this paper, we study the capacity-achieving input covariance matrices for the jointly-correlated (or the Weichselberger) Rician fading multiple-input multiple-output (MIMO) a...

Prediction of discrete cosine transformed coefficients in resized pixel blocks
Abstract— A hybrid model was developed to predict the zeroquantized discrete cosine transform (ZQDCT) coefficients for intra blocks in our previous work. However, the complicated...
