Bregman divergence geometry
The post shares a visual explainer on the geometry of Bregman divergences, highlighting:
- 3-point and 4-point identities as a parallelogram-like identity
- generalized Pythagorean theorem
- Hessian metric tensor and parallel transport
- geodesic triangles and a “double Pythagoras” relation
The image frames these facts as a geometric toolkit for understanding Bregman manifolds and their coordinate structure.
