报告摘要：Uncertainty is inherent in data generation processes, whether arising from stochastic dynamics, limited samples, or complex multi-scale interactions. Understanding how structured patterns emerge from such uncertainties is a central challenge in generative modeling. This report explores this question through the lens of dynamics, geometry, and topology, with a particular focus on early warning prediction.

We investigate the mechanisms underlying critical transitions in generative models, including mode collapse and vector field splitting, which manifest as topological changes across scales. Building upon the Onsager–Machlup action functional and Schrödinger bridge theory, we introduce entropy-based indicators defined in the space of probability measures to assess and anticipate such transitions.  In parallel, we examine how geometric properties of latent spaces can be exploited to improve few-shot generation, where data scarcity amplifies uncertainty. By imposing geometric constraints on latent flows, we achieve more stable training and better mode coverage. Together, these perspectives—dynamical, geometrical, and topological—offer a unified framework for understanding how certainties emerge from uncertainties, and suggest new directions for building robust and interpretable generative models.
