Question 16
Classifier-free guidance is a technique used in diffusion models to improve sample quality without the explicit use of a classifier. This technique involves modifying the sampling process based on a control parameter. If the control parameter, denoted as γ, is set to zero, what effect does this have on the generation process?
It fails to generate realistic samples
It removes all guidance, effectively making the process equivalent to the unconditional generation.
It maximizes the influence of the classifier, leading to highly detailed generations.
It can lead to more diverse samples compared to higher values of γ, as the generation process is less constrained by the conditional information.
