We present an application of message-passing techniques to gene regulatory network inference. The network inference is posed as a constrained linear regression problem, and solved by a distributed computationally efficient message-passing algorithm. Performance of the proposed algorithm is tested on gold standard data sets and evaluated using metrics provided by the DREAM2 challenge. Performance of...
A new class of message-passing algorithms for motif finding is presented. Motif finding is the problem of identifying a collection of common subsequences within a given set of DNA sequences. It can be cast as an integer linear program (ILP). Message-passing techniques are a computationally efficient alternative to the often infeasible combinatorial solutions to the ILP. We introduce a new graphical...
A message-passing algorithm for motif finding is presented. Motif finding stands for the problem of identifying a collection of common subsequences within a given set of DNA sequences. Using a combinatorial framework for this problem, this paper describes it in terms of a graphical model. Subsequently, an inference problem is formulated over this graphical representation for the motif finding problem...
