Webb16 mars 2024 · Our investigation starts with the probability simplex (probability manifold) supported on vertices of a finite graph. The main idea is to embed the probability manifold as a submanifold of the positive measure space with a nonlinear metric tensor. Here the nonlinearity comes from the linear weighted Laplacian operator.

Each arrow starts at the uncalibrated probabilities and end with the arrow head at the calibrated probability. The color of the arrow represents the true class of that test sample.
