The Time-Invariant Multidimensional Gaussian Sequential Rate-Distortion Problem Revisited
Photios A. Stavrou, Takashi Tanaka, Sekhar Tatikonda
We revisit the sequential rate-distortion (SRD) trade-off problem for vector-valued Gauss-Markov sources with mean-squared error distortion constraints. We show via a counterexampl…
Accelerated Consensus via Min-Sum Splitting
Patrick Rebeschini, Sekhar Tatikonda
We apply the Min-Sum message-passing protocol to solve the consensus problem in distributed optimization. We show that while the ordinary Min-Sum algorithm does not converge, a mod…
A New Approach to Laplacian Solvers and Flow Problems
Patrick Rebeschini, Sekhar Tatikonda
This paper investigates the behavior of the Min-Sum message passing scheme to solve systems of linear equations in the Laplacian matrices of graphs and to compute electric flows. V…
Locality in Network Optimization
Patrick Rebeschini, Sekhar Tatikonda
In probability theory and statistics notions of correlation among random variables, decay of correlation, and bias-variance trade-off are fundamental. In this work we introduce ana…
