Researchers have developed a new method for sampling from diffusion models that encourages diversity among the generated outputs. This approach, called Variance-Tilted Diffusion Models, uses a variance-weighted batch distribution to favor sets of samples with a large empirical spread after a linear feature map. The sampler is derived as a Doob h-transform of independent diffusion dynamics, incorporating an interaction term that repels posterior denoised means and a curvature term that shifts particles towards regions of higher feature variance.
