New algorithm estimates Lipschitz functions with near-optimal convergence rates

This paper introduces a new algorithm for estimating Lipschitz functions from noisy data, achieving near-optimal convergence rates. The method extends existing techniques for convex shape-restricted regression by employing a nonlinear feature expansion that maps functions into a delta-convex class. This approach allows for adaptive partitioning to determine intrinsic data dimensions and uses a penalty-based regularization that bypasses the need to know the true Lipschitz constant. Experimental results show competitive performance against established methods like nearest-neighbor and kernel-based regressors. AI
