    Machine learning and topological data analysis identify unique features of human papillae in 3D scans by Rayna Andreeva, Anwesha Sarkar, Rik Sarkar

    Published 2023-12-01
    “…The finer differences in shapes of papillae are investigated computationally based on a number of features derived from discrete differential geometry and computational topology. Interpretable machine learning techniques show that persistent homology features of the papillae shape are the most effective in predicting the biological variables. …”

    Persistent homology analysis of type 2 diabetes genome-wide association studies in protein–protein interaction networks by Euijun Song, Euijun Song

    Published 2023-09-01
    “…The 1-dimensional persistent T2D disease module comprising these 18 persistent 1-dimensional holes is significantly larger than that expected by chance (59 nodes and 83 edges, P<0.001), indicating a significant topological structure in the PPI network. Our computational topology framework potentially possesses broad applicability to other complex phenotypes in identifying topological features that play an important role in disease pathobiology.…”
