Stable Generative Model
A score-based generative model driven by an α-stable Lévy process, which replaces Brownian motion as the driver of forward noising and backward denoising. It is suited to modeling heavy-tailed data.

Brownian diffusion models may systematically underestimate the probability of extreme events in heavy-tailed data scenarios, whereas stable models can correctly extrapolate to the tail region when α=ν.
