Hamiltonian Neural Networks show improved long-horizon prediction accuracy

Researchers have evaluated Hamiltonian Neural Networks (HNNs) against standard feedforward networks for predicting pendulum and Kepler dynamics. By using identical training data, optimization settings, and integration schemes, the study found that HNNs significantly reduce energy drift and trajectory mean squared error over long prediction horizons. The HNNs demonstrated a 42-fold reduction in energy drift and a 15.8-fold reduction in trajectory MSE on the pendulum task, with performance improvements becoming more pronounced in nonlinear regions of phase space. Similar benefits in prediction accuracy and physical consistency were observed for the Kepler two-body problem. AI
