This post delves into the theoretical underpinnings of natural latents, focusing on the exact prices for approximate natural latents in the context of jointly Gaussian views. It introduces a distribution-free sum rule derived from the chain rule for mutual information, which establishes a fundamental relationship between mediation error and remainder error. The work then presents an exact tradeoff curve for these errors, demonstrating that the minimum achievable error is constrained by the correlation of the views, particularly in the jointly Gaussian case.
