Fig. 1 (IMAGE) Osaka University Caption From left to right, the trajectory of a double pendulum, the prediction results using a conventional artificial neural network, and those using the method proposed in this study. The conventional artificial neural network was unable to discover that the length of the pendulum rod remains constant, and errors accumulated over time. The proposed method found and preserved this law. Credit Takashi Matsubara, Takaharu Yaguchi Usage Restrictions Credit must be given to the creator.
