文摘

The SOMersault is a modification to the self-organizing map (SOM) method. Environmental data sets often contain inherent lower dimensional nonlinear manifolds. The SOMersault can cluster and visualise data sets containing nonlinear manifolds. Patterns are extracted by ‘unrolling’ the map along the geodesic surface. The SOMersault is demonstrated on a global data set of river basins.
