What the math gives to ML

The paper's transferable asset is a formal method for certifying that a mathematical reformulation preserves feasible solutions and the ordering of global objectives rather than merely matching empirical solver outputs. This can be adapted to neural-network graph rewrites, structured pruning, parameter tying, and loss-preserving reparameterizations by treating the original and transformed models as two constrained optimization problems. The most practical first target is small piecewise-linear subnetworks or compression transformations, where bounded SMT queries can certify exact functional or objective-order equivalence and reject unsafe compiler transformations before large-scale training.

SMT-Certified Loss-Preserving Network Rewrites

Represent an original neural-network block and a proposed rewritten block as constrained optimization formulations over inputs and trainable parameters, then certify that the rewrite preserves feasibility and the ordering of losses over a bounded domain. This gives a compiler or pruning pipeline a formal reject/accept gate instead of relying only on numerical regression tests.
