The PolyexponentialScheduler node is designed to generate a sequence of noise levels (sigmas) based on a polyexponential noise schedule. This schedule is a polynomial function in the logarithm of sigma, allowing for a flexible and customizable progression of noise levels throughout the diffusion process.Documentation Index

Inputs
| Parameter | Data Type | Description |
|---|---|---|
steps | INT | Specifies the number of steps in the diffusion process, affecting the granularity of the generated noise levels. |
sigma_max | FLOAT | The maximum noise level, setting the upper bound of the noise schedule. |
sigma_min | FLOAT | The minimum noise level, setting the lower bound of the noise schedule. |
rho | FLOAT | A parameter that controls the shape of the polyexponential noise schedule, influencing how noise levels progress between the minimum and maximum values. |
Outputs
| Parameter | Data Type | Description |
|---|---|---|
sigmas | SIGMAS | The output is a sequence of noise levels (sigmas) tailored to the specified polyexponential noise schedule. |
