Abstract Background A genetic network can be represented as a directed graph in which a node corresponds to a gene and a directed edge specifies the direction of influence of one gene on another. The reconstruction of such networks from transcript profiling data remains an important yet challenging endeavor. A transcript profile specifies the abundances of many genes in a biological sample of interest. Prevailing strategies for learning the structure of a genetic network from highdimensional transcript profiling data assume sparsity and linearity. Many methods consider relatively small directed graphs inferring graphs with up to a few hundred nodes. This work examines large undirected graphs representations of .
