Solving a class of stochastic optimal control problems by physics-informed neural networks
This addresses computational challenges in stochastic control for fields like finance and engineering, though it appears incremental as it builds on existing physics-informed neural network approaches.
The authors tackled high-dimensional stochastic optimal control problems by developing a physics-informed neural network method based on the Hamilton-Jacobi-Bellman equation, achieving efficient and applicable results across various applications.
The aim of this work is to develop a deep learning method for solving high-dimensional stochastic control problems based on the Hamilton--Jacobi--Bellman (HJB) equation and physics-informed learning. Our approach is to parameterize the feedback control and the value function using a decoupled neural network with multiple outputs. We train this network by using a loss function with penalty terms that enforce the HJB equation along the sampled trajectories generated by the controlled system. More significantly, numerical results on various applications are carried out to demonstrate that the proposed approach is efficient and applicable.
