You’re talking about the score function, right? Which is the derivative of the log probability density function. I dunno how to get from there to a utility function interpretation. Like, we don’t produce samples from the model by globally maximizing over the PDF (at worst, trying that might produce an adversarial example, and at best, that would sample the “most modal” image).

ah, okay. yup, you’re right, that’s what I was referring to. I am now convinced I was wrong in my original comment!
