Figure 7: Heat maps for the discrete Drosophila data. Graphical heat map representations of the temporal connectivity structures for the Drosophila melanogaster data. (a) Heat matrix inferred with the BDM model. (b) Heat matrix inferred with the novel changepoint variant . Each heat map indicates the posterior probability of two time points being assigned to the same compartment (mixture component). The probabilities are represented by a grey shading, where white corresponds to a probability of , and black corresponds to a probability of . The numbers on the axes represent the time points of the time course experiment. Both axes have been ticked at the three real morphological stage transitions: embryonic to larval (), larval to pupal (), and pupal to adult ().
