    Spectral Feedback for Test-Time Alignment of Protein Diffusion Models

    A new framework for precise protein design using spectral analysis during the diffusion reverse process

    Reward maximization alignment methods for discrete diffusion models have primarily focused on steering the reverse process, either by influencing token logits or by selecting favorable sequences at intermediate steps. These approaches largely treat inference as a unidirectional p...
