UnverifiedCFG performs conditional and unconditional predictions separately during inference and interpolates and amplifies them via the formula output = uncond + guidance_scale × (cond - uncond), at the cost of requiring two forward passes per step.76% similarUnverifiedClassifier-free guidance (CFG) originally came from diffusion generative models; the approach is to compute both conditional and unconditional predictions during sampling, then use a weight w to amplify the difference between them, with the formula ε = ε_uncond + w·(ε_cond − ε_uncond).73% similarUnverifiedCFG is a core hyperparameter in diffusion models, rooted in a 2022 research finding, and works by enhancing responsiveness to text descriptions through a weighted mixture of the predictions from the conditional and unconditional denoising paths.73% similarUnverifiedClassifier-Free Guidance (CFG) is one of the most mainstream guidance techniques in diffusion models and flow matching models, discarding conditions with a certain probability during training and, during sampling, subtracting the unconditional prediction from the conditional one via a formula and amplifying the guidance strength.67% similarUnverifiedConformal prediction is an uncertainty quantification framework that outputs prediction sets or prediction intervals with rigorous statistical coverage guarantees.66% similar
