What the math gives to ML

The paper gives a constructive method for lifting rational-like computations into a larger state space with explicit algebraic constraints. Its transferable asset is the Jacobian-based tangent update that keeps auxiliary variables on the constraint manifold while the primary state evolves. This can become a constrained residual or recurrent layer in which rational features remain algebraically consistent over many layers instead of drifting under discretization. The most useful initial target is a deep residual MLP or neural state-space model using rational activations, with projection and constraint-residual ablations.

Algebraic-Invariant Residual Layer

Represent a rational-like feature transformation with an auxiliary state y constrained by polynomial equations G(x,y)=0, and update x and y jointly along the tangent space of that constraint manifold. This creates residual blocks in which nonlinear feature identities remain consistent over many layers or time steps, reducing auxiliary-variable drift and potentially stabilizing rational activations and implicit recurrent dynamics.
