New deep learning algorithm tackles high-dimensional dynamic programming problems

Researchers have developed a novel deep learning algorithm called Certainty Equivalent Learning (CEL) to tackle complex, high-dimensional dynamic programming problems with recursive utility. This mesh-free, simulation-based approach directly learns the certainty-equivalent value using neural networks, bypassing the need for explicit representations or differentiability of state transitions. The CEL algorithm has demonstrated accurate approximations for value and policy functions across various financial applications, including robust control and asset allocation, achieving Bellman errors in the range of 1.0e-4 to 1.0e-3. AI
