Researchers have analyzed the convergence properties of Stochastic Gradient Descent (SGD) when applied to score-based generative models (SGMs). The study establishes a non-convex convergence rate for SGD on the weighted denoising score-matching objective, considering schedule-dependent weighting factors. Additionally, for overparameterized two-layer ReLU networks, a Neural Tangent Kernel analysis was developed to provide score-approximation error bounds along the SGD trajectory. The findings offer theoretical guidance on the impact of reweighting factors in score approximation errors for practical applications. AI
