LatticeSMC: Where to Spend Inference-Time Compute in Chunked Sequence Generators
Xuanchen Wang, Heng Wang, Weidong Cai
Long-form generators for music, motion and video produce sequences chunk by chunk, with each chunk generated by iterative denoising while rewards are defined over the full sequence…
