    • 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 ...
    • Graphical Models via Univariate Exponential Family Distributions 

      Yang, Eunho; Ravikumar, Pradeep; Allen, Genevera I.; Liu, Zhandong (2015)
      Undirected graphical models, or Markov networks, are a popular class of statistical models, used in a wide variety of applications. Popular instances of this class include Gaussian graphical models and Ising models. In ...
    • Inferring metabolic networks using the Bayesian adaptive graphical lasso with informative priors 

      Peterson, Christine; Vannucci, Marina; Karakas, Cemal; Choi, William; Ma, Lihua; Maletic-Savatic, Mirjana (2013)
      Metabolic processes are essential for cellular function and survival. We are interested in inferring a metabolic network in activated microglia, a major neuroimmune cell in the brain responsible for the neuroinflammation ...
    • 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 ...
    • 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 ...
