Paper Abstract:      In this paper we perform a study of the performance of the VBEM algorithm proposed in [19]. The VBEM is a Bayesian approach for reconstructing gene regulatory networks (GRNs) based on microarray data. We focus on a variable selection formulation and develop a solution by a variational Bayes Expectation Maximization (VBEM) learning rule. The major advantage of the VBEM solution over Monte Carlo sampling based approach is its lower computational complexity. This makes it appealing for uncovering large networks. The suitability of the proposed algorithm to infer large networks is studied in terms of its ROC curves.
