Rbf surrogate
WebOct 23, 2014 · Sequential RBF surrogate-based efficient optimization method for engineering design problems with expensive black-box functions. Lei Peng 1,2, Li Liu 1,2, … WebDiffusion models have recently been shown to generate high-quality synthetic images, especially when paired with a guidance technique to trade off diversity for fidelity. We explore diffusion models for the problem of text-conditional image synthesis and compare two different guidance strategies: CLIP guidance and classifier-free guidance. We find …
