The VPScheduler node is designed to generate a sequence of noise levels (sigmas) based on the Variance Preserving (VP) scheduling method. This sequence is crucial for guiding the denoising process in diffusion models, allowing for controlled generation of images or other data types.

Inputs

ParameterDescriptionData Type
stepsSpecifies the number of steps in the diffusion process, affecting the granularity of the generated noise levels.INT
beta_dDetermines the overall noise level distribution, influencing the variance of the generated noise levels.FLOAT
beta_minSets the minimum boundary for the noise level, ensuring the noise does not fall below a certain threshold.FLOAT
eps_sAdjusts the starting epsilon value, fine-tuning the initial noise level in the diffusion process.FLOAT

Outputs

ParameterDescriptionData Type
sigmasA sequence of noise levels (sigmas) generated based on the VP scheduling method, used to guide the denoising process in diffusion models.SIGMAS
