Researchers have developed Intrinsic Green's Learning (IGL), a novel framework for supervised learning on manifolds. IGL models a target function on a manifold as the solution to a linear partial differential equation (PDE) by learning its source term from data. The method employs an encoder to discover a low-dimensional coordinate chart on the manifold, enabling the decomposition of the source and Green's kernel into low-rank tensors. This approach reduces a high-dimensional integral to independent one-dimensional integrals, with computational cost linear in the manifold's intrinsic dimension. A two-stage algorithm separates coordinate discovery from source fitting, and learnable gates automatically determine the intrinsic dimension, as demonstrated by near-optimal classification and intrinsic dimension recovery on MNIST.
