Researchers have developed a novel method for adapting neural network architectures by treating training as a continuous-time optimal control problem. This approach uses a posteriori error estimation to identify layers where new layers should be inserted to improve approximation error. The framework introduces a new architecture where weights and biases are piecewise linear functions across layers, and it leverages dual weighted residual methodology for error bounding. The method has demonstrated superior generalization performance on scientific datasets, including learning mappings for the Navier-Stokes equation, outperforming existing adaptation techniques. AI
