Researchers have established a functional central limit theorem for kernel gradient flow and infinitesimal gradient boosting. This theorem details the fluctuations of the process around its deterministic limit, showing that rescaled deviations converge to a Gaussian process. The analysis was conducted within a reproducing kernel Hilbert space, characterizing the boosting process as a solution to an ordinary differential equation. The methodology, which involves a general stochastic perturbation analysis of ODEs in Banach spaces, is applicable to other areas and was first demonstrated on kernel gradient flow before being applied to the more complex gradient boosting setting.
