Figure 1. Overview of our approach to integrate diverse regulatory genomic datasets as structure priors. Xi and X j denote a regulator (such as a transcription factor) and a target gene respectively. For each candidate edge Xi → X j , different sources of prior networks can be used. The figure shows three
different types of prior networks: ChIP, Motif and Knockout. Each prior network can be weighted, for example wi,Mj denotes the weight of the regulatory
edge in the motif network. Different prior networks are combined to specify the prior probability of an edge using a single logistic function with prior parameters ␤0 , ␤M , ␤K , ␤C . ␤◦ controls for network sparsity, while the other parameters specify importance of the prior networks. The regulatory network is
itself represented as a dependency network learned by estimating a set of conditional probability distributions. In the example, the conditional distribution
of the target gene X4 is specified by three regulators, X1 , X2 , X3 . denotes a particular form of conditional probability distributions that is parameterized
by .
