New research analyzes SGD convergence for score-based generative models

By PulseAugur Editorial · [2 sources] ·

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

IMPACT Provides theoretical guidance for optimizing score-based generative models, potentially improving training efficiency and performance.
