Question 21

+2 marksNumerical answer

Consider a reverse process in a diffusion model where the goal is to reconstruct the original data from the noise. If the model correctly reduces the variance of the noise by 0.02 in each reverse step, and starts with a noise variance of 1.0 at timestep T = 50, how many steps are required to reduce the noise variance to 0.1 _______________ ?
