Weighted Adjoint Matching: Finetuning Flow Matching Models with Time-Dependent Control Cost
arXiv:2610.20035v1 Announce Type: new Abstract: We introduce Weighted Adjoint Matching, a method to finetune a pretrained diffusion or flow matching model given a differentiable reward. We derive it from Adjoint Matching, which reformulates finetuning as a stochastic optimal control problem with a…
