Extended Data Fig. 1: Methods graphical summary and effects of computer simulated diversity increases.
From: Impacts of speciation and extinction measured by an evolutionary decay clock
a, Graphical summary of the ML method. b–g, Computer simulations of secular variation in diversity, testing effects on measures of co-occurrence structure used in this study. b–g, Linear (b–d) and exponential (e–g) diversity increases (Supplementary Computer Code 3). b, e, Heatmaps visualizing the machine learnt spatial embedding distance between mean species locations at different times: yellow, closest; purple, farthest. c, f, Plot of embedding distances between successive times. d, g, Plot of first two principal component axes from the 16-dimensional spatial embedding. ML training times were 3,000 training epochs.
