What the math gives to ML
The paper provides a global geometric signature for planar shapes: the full pairwise-distance distribution, equivalently its Mellin transform/Riesz energy function, generically identifies polygonal domains up to Euclidean isometry. The transferable asset is not merely another distance metric, but a theoretically motivated, transformation-invariant multiscale signature whose singular or rapidly varying behavior encodes geometric events such as side lengths and angles. A practical neural adaptation is to add a sampled Riesz-energy or distance-distribution matching loss to polygon or shape reconstruction, yielding an alignment-free global constraint that complements local pixel, Chamfer, or vertex losses.

Add a transformation-invariant global shape loss based on the interpoint-distance distribution or its Riesz-energy transform to a network that predicts polygon vertices or masks. Matching this signature forces the prediction to reproduce global side-length and angle structure even when local vertex correspondence is ambiguous, while random translations, rotations, and reflections require no alignment preprocessing. The uniqueness guarantee applies to generic polygonal domains, so this should be…
