Fig. 3: MINIE’s performance on nonlinear multi-omic model.

a Multi-omic network of genes (purple) and metabolites (green). Solid arrows depict interactions to be inferred by MINIE, while dashed arrows indicate known metabolic interactions input as prior knowledge. b Artificially-generated transcriptomic (left) and metabolomic (right) data by the BoolODE algorithm. Left: Projection of the single-cell data using PCA. The arrow shows the pseudotime trajectory estimated by MINIE. Right: Bulk metabolic concentrations (dots) and inferred metabolomic trajectories (dashed lines) using the mapping Γ. c Histogram of predicted probability values for the existence of each link, where true positive links are represented by a dark shade. d Reconstructed network based on predicted probabilities for ε = 0.4. The true links (solid green), false positives (dotted grey), and false negatives (solid grey) are represented by arrows weighted according to the confidence value predicted by MINIE.
