New research frames Adjoint Matching via Stochastic Maximum Principle

A new research paper, "Adjoint Matching through the Lens of the Stochastic Maximum Principle in Optimal Control," by Jiequn Han, rigorously derives and generalizes the Adjoint Matching method for stochastic optimal control problems. The work formulates a Hamiltonian adjoint matching objective and demonstrates its connection to the Hamilton-Jacobi-Bellman stationarity conditions. For cases with state- and control-independent diffusion, the paper recovers a previously introduced lean adjoint matching loss, while highlighting the necessity of additional terms when diffusion is state-dependent. The research offers a practical, implementable alternative to traditional Stochastic Maximum Principle algorithms, particularly in stochastic settings where martingale terms pose challenges. AI

    Adjoint Matching through the Lens of the Stochastic Maximum Principle in Optimal Control

    arXiv:2604.08580v2 Announce Type: replace-cross Abstract: Reward fine-tuning of diffusion and flow models and sampling from tilted or Boltzmann distributions can both be formulated as stochastic optimal control (SOC) problems, where learning an optimal generative dynamics corresp…
