Improved Wavelet Denoising via Empirical Wiener Filtering
(1997-07-01)Wavelet shrinkage is a signal estimation technique that exploits the remarkable abilities of the wavelet transform for signal compression. Wavelet shrinkage using thresholding is asymptotically optimal in a minimax ... -
Robust Distributed Estimation in Sensor Networks using the Embedded Polygons Algorithm
(2004-04-01)We propose a new iterative distributed algorithm for linear minimum mean-squared-error (LMMSE) estimation in sensor networks whose measurements follow a Gaussian hidden Markov graphical model with cycles. The <i>embedded ... -
Robust Distributed Estimation Using the Embedded Subgraphs Algorithm
(2006-08-01)We propose a new iterative, distributed approach for linear minimum mean-square-error (LMMSE) estimation in graphical models with cycles. The embedded subgraphs algorithm (ESA) decomposes a loopy graphical model into a ...
