Claims

C1strongest claim

We introduce a new family of principled learnable geometric features for point clouds called neural point-forms (NPFs). [...] We make this intuition precise by proving the long-run consistency of comparison matrices under standard sampling, bandwidth, density, and manifold-hypothesis assumptions. This yields a compact, efficient and permutation-invariant neural layer whose output is a learned form-comparison matrix.

C2weakest assumption

The long-run consistency of comparison matrices holds under standard sampling, bandwidth, density, and manifold-hypothesis assumptions, as invoked to justify the theoretical foundation for the neural layer.

C3one line summary

Neural point-forms are introduced as permutation-invariant neural layers that output learned form-comparison matrices for point clouds, with a claimed consistency proof under sampling and manifold assumptions and competitive results on synthetic and biological data.
