Researchers have developed a Low-Rank Evolutionary Deep Neural Network (LR-EDNN) method to significantly reduce the computational cost of solving time-dependent partial differential equations. This new approach achieves this by employing adaptive tangent-space projection, which replaces the dense linear system solution required in traditional Evolutionary Deep Neural Networks (EDNNs) with a more efficient linear reduced problem. The LR-EDNN method constructs the reduced Jacobian through layerwise Jacobian-vector products, avoiding the formation of the full Jacobian. Numerical experiments indicate that LR-EDNN substantially cuts computational expenses while maintaining accuracy and fidelity when an adequate rank is selected. AI
