New Residual Algebra learning method boosts stock returns

Researchers have developed a new learning framework called Residual Algebra, which moves beyond simple feature concatenation to preserve the origin of representation errors. This method treats representations as typed objects that manage their own coordinate systems and unresolved residuals. The algebra is realized through a relax-aggregate-close process, where corrected fields converge to a shared mean, creating an identity-erasure boundary. Applied to 3.67 million Chinese A-share stock-day observations, this approach significantly improved net-of-cost returns from 13.52% to 19.10% and boosted the Sharpe ratio from 1.42 to 2.09, demonstrating the value of explicit residual ownership and composition. AI

IMPACT This novel learning framework could offer improved analytical capabilities for financial markets by explicitly managing representation errors.

    Residual Algebra for Representation-Preserving Learning

    arXiv:2608.07349v1 Announce Type: new Abstract: Learning from heterogeneous representations is usually reduced to feature concatenation, which erases which representation produced an error. We instead algebraize the residual: a representation is a typed object that owns both a co…
