Figure 1From: Bayesian non-negative factor analysis for reconstructing transcription factor mediated regulatory networks Graphical model . The Bayesian graphical model is shown here. y n is the observed mRNA gene microarray data, the prior probability of regulation π g , l is extracted from TRANSFAC database, α n , β n , λ 0, α, αa, β a are the hyperparameters, and the rest variables are unknown and need to be estimated.Back to article page
