Diffusion short course bug

helper function: perturbs an image to a specified noise level

def perturb_input(x, t, noise):
return ab_t.sqrt()[t, None, None, None] * x + (1 - ab_t[t, None, None, None]) * noise

I’m pretty sure it should be 1-ab_t.sqrt(). Submitting here because the website won’t let me create course q&a.
