What the math gives to ML

The paper gives an explicit calculus for how several simultaneous boundary singularities combine: product interactions add active exponents, while sum interactions are controlled by the largest exponent. The resulting finite-distance thresholds and snowflake exponents provide a principled way to construct feature-space metrics that deliberately stretch or compress representations near multiple soft constraints. A plausible neural transfer is a boundary-aware metric-learning regularizer in which network outputs expose nonnegative boundary coordinates and pairwise distances are weighted by the product or sum conformal law. This is not a drop-in replacement for ordinary losses, but it yields falsifiable experiments on whether corner-aware geometry improves robustness and representation quality near intersecting data regimes.

Corner-Snowflake Metric Learning

Add a metric-learning loss whose local geometry changes according to several learned or supplied boundary coordinates. Use a product conformal factor when violations of multiple constraints should accumulate, or a sum conformal factor when the most severe constraint should dominate; on a face where several coordinates vanish, impose the corresponding snowflake exponent on tangential distances.
