A prior-free blind detection of information leakage from model predictions
Laurence A. Jacobs
Data leakage -- contamination of a model with information unavailable at baseline -- is the dominant reproducibility failure in machine-learning-based science, yet detection tools…

Multicriticality and Scaling: Mellin Spectral Theory, and the Decoupling of Geometric and Spectral Exponents
Laurence A. Jacobs, Alejandro Frank
We develop a spectral theory of scale-invariant operators on the multiplicative half-line . A symmetric kernel satisfying $M(kx, ky) = k^{-a}M(x, y)…

Temporal Matrix Scale Invariance and the Classification of Tipping Points
Alejandro Frank, Laurence A. Jacobs
We introduce temporal matrix scale invariance (tMSI), a mathematical structure for the two-time correlation kernel of a multivariate observable. A kernel satisfies tMSI o…
