On the tracking performance of combinations of least mean squares and recursive least squares adaptive filters
Combinations of adaptive filters have attracted attention as a simple solution to improve filter performance, including tracking properties. In this paper, we consider combinati...

A non-iterative estimator for the concentration parameter of the relative phase distribution
In this paper, we propose an approximation of the relative phase probability function (RP pdf) and use it to find a non-iterative estimator for the concentration parameter of the...

Approximate nearest neighbors using sparse representations
A new method is introduced that makes use of sparse image representations to search for approximate nearest neighbors (ANN) under the normalized inner-product distance. The approa...

Optimize the obvious: Automatic call flow generation
In commercial spoken dialog systems, call flows are built by call flow designers implementing a predefined business logic. While it may appear obvious from this logic how the c...

On linear versus non-linear magnitude-DFT estimators and the influence of super-Gaussian speech priors
Although the linear mean-squared error (MSE) complex-DFT estimator, i.e., the Wiener filter, is well-known, its magnitude-DFT (MDFT) counterpart has never been considered in the ...
