Jacobian-Velocity Bounds for Deployment Risk Under Covariate Drift
Jonathan R. Landers
We study long-horizon deployment of a frozen predictor under dynamic covariate shift. A time-domain Poincare inequality first reduces temporal risk volatility to derivative energy.…

Closed-Form Beta Distribution Estimation from Sparse Statistics with Random Forest Implicit Regularization
Jonathan R. Landers
This work advances distribution recovery from sparse data and ensemble classification through three main contributions. First, we introduce a closed-form estimator that reconstruct…

Sorting as Gradient Flow on the Permutohedron
Jonathan Landers, Jonathan Robert Landers
We investigate how sorting algorithms navigate the complexity of permutation space. Our main contribution is a continuous-time geometric model that casts sorting as directed motion…
