Researchers have developed LatticeSMC, a novel sampling method designed to optimize inference-time compute for sequence generators that produce output in chunks, such as those for music, motion, and video. This method leverages a Feynman-Kac model on a two-dimensional lattice representing chunk index and denoising steps, allowing for exact design choices based on reward structures. LatticeSMC demonstrates significant improvements in metrics like beat alignment and prompt adherence for text-to-music generation tasks, outperforming existing methods like best-of-N sampling under matched computational budgets.
