Fig. 1From: Large sample size and nonlinear sparse models outline epistatic effects in inflammatory bowel diseasePanel overview of NN architectures, each build on top of the shared gene module with increasing complexity. Panel A shows NNlogreg, the simplest architecture connecting the gene neurons G directly to the output, implementing a LogReg of the |G| neurons. Panel B illustrates NNbiosparse with connections between gene neurons G and pathway neurons P based on the KEGG database. The model in panel C, NNdense, adds a fully connected hidden layer to increase model expressivenessBack to article page
