New framework unifies and analyzes Learn-Then-Differentiate gradient estimation

A new framework for Learn-Then-Differentiate (LTD) gradient estimation has been developed, unifying existing methods and providing accuracy guarantees. This framework explains what LTD differentiates and how accurately it estimates gradients, particularly for models with weighted representations. The research demonstrates that accuracy guarantees for fitted models translate to gradient accuracy, approaching standard Monte Carlo rates under specific smoothness conditions. This unified approach encompasses established techniques like kernel regression and kernel ridge regression, while also offering new insights for multiple kernel learning and smooth neural networks.
