FIG. 6.

Two example results of the temporal GPTwoSample model on the Arabidopsis data. (Bottom panel) Inferred posterior distributions from the Gaussian processes (blue, the process describing the shared biological behavior; red and green, the two separate processes modelling differential gene expression). (Top panel) The Hinton diagrams indicate whether, at a given point in time, the gene is likely to be differentially expressed or not. The size of the dots in each row is proportional to the probability of differential expression (top row) and of no differential expression (bottom row).
