Extended Data Fig. 5: Cluster assignments computed by Neural ADMIXTURE for individuals born outside the British and Irish Isles in the UK Biobank training data.
(a) K=2 (b) K=3 (c) K=4 (d) K=5 (e) K=6. Because the majority of the dataset is composed of individuals with white British ancestry, we only plot the cluster assignments of individuals that reported a country-of-birth outside British and Irish Isles. We can observe that K=2 approximately divides samples between European and non-European populations. With K=3 European, South-and-East Asian, and African ancestry clusters emerge. When K=4 a fine-grained clustering emerges dividing East and South Asian populations. K=5 adds a fifth cluster shared in common (with different proportions) between Southern European (Mediterranean) and West Asian (Near Eastern) populations. Finally, K=6 seems to introduce a cluster mostly present in Northern and Eastern European populations.
