  • Robust Distributed Estimation Using the Embedded Subgraphs Algorithm 

    Delouille, Veronique; Neelamani, Ramesh; Baraniuk, Richard G. (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 ...
  • Distributed Wavelet Transform for Irregular Sensor Network Grids 

    Wagner, Raymond; Choi, Hyeokho; Baraniuk, Richard G.; Delouille, Veronique (2005-07-01)
    Wavelet-based distributed data processing holds much promise for sensor networks; however, irregular sensor node placement precludes the direct application of standard wavelet techniques. In this paper, we develop a new ...
  • Robust Distributed Estimation in Sensor Networks using the Embedded Polygons Algorithm 

    Delouille, Veronique; Neelamani, Ramesh; Baraniuk, Richard G. (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 ...
  • The Embedded Triangles Algorithm for Distributed Estimation in Sensor Networks 

    Delouille, Veronique; Neelamani, Ramesh; Chandrasekaran, Venkat; Baraniuk, Richard G. (2003-09-01)
    We propose a new iterative distributed estimation algorithm for Gaussian hidden Markov graphical models with loops. We decompose a loopy graph into a number of linked <i>embedded triangles</i> and then apply a parallel ...
