What the math gives to ML
The paper constructs a random directional field whose output is a sum of heavy-tailed vector increments gated by spherical half-spaces, and proves that its image has almost-sure Hausdorff dimension exactly $(d-1)\alpha$. The transferable asset is the explicit multiscale separation between a finite set of large jumps, which induces a hyperplane arrangement, and a small-jump residual that controls local image diameters. This suggests a finite neural feature or routing layer in which large random vectors define discrete angular cells while a truncated stable residual supplies within-cell variation, with the truncation level controlling compute, memory, and approximation error.

Replace a dense directional feature map with a finite stable-zonotope layer: a small set of large random vectors creates a hyperplane arrangement over the input sphere, while a cheaper small-jump residual gives continuous features inside each cell. The layer exposes an explicit compute-versus-resolution knob through the jump cutoff and can be used either as an embedding before an MLP or as a lightweight router for mixture-of-experts blocks.
