When Do PINNs Beat Classical Numerical Methods? A 1D vs 5D Experiment

A physics-informed neural network (PINN) was benchmarked against a plain finite-difference solver in two experiments, one in 1D and one in 5D, with the winning method changing between the two dimensions, according to a Towards Data Science report. The comparison found that the PINN did not consistently beat the classical numerical method across both dimensionalities.
