What the math gives to ML

The paper develops an asymmetric, measure-aware notion of functional domination: a target family of observables is considered representable by a source family when, under a coupling, almost all mass lies on pairs where every target observable is uniformly approximated by some source observable. The transferable asset is the combination of one-sided approximation, trimmed high-probability support, and an explicit worst-case error, rather than ordinary symmetric feature matching. This suggests a robust asymmetric distillation or domain-adaptation loss in which teacher observables must be recoverable from student features on a learned high-mass coupling while a small fraction of mismatched examples is ignored. The construction is useful when the target contains information the source should preserve, but exact pointwise correspondence is unavailable or contaminated by outliers.

Trimmed One-Sided Observable Domination

Add an asymmetric distillation loss that requires target or teacher observables to be approximable by source or student observables on only a 1-epsilon mass subset of a coupling. Unlike symmetric feature alignment, the student is penalized only for failing to reproduce target functions on well-matched mass, making the objective robust to outliers, label noise, and partial domain mismatch. The inner minimization allows each target observable to select its best source probe rather than forcing a…
