Deep learning has been widely used as a data-driven modeling method for dynamical systems. However, existing modeling approaches are limited by the fixed input-output causality of system components, which makes it difficult to apply them to complex tasks such as inverse design and interconnection of subsystems. To address this limitation, we propose a modeling method for dynamical systems based on the kernel representation of Dirac structures using deep learning. Since this method describes the system in a form that does not fix input-output causality, it can be flexibly applied to inverse design. Furthermore, by algebraically coupling pre-trained models without retraining, we can efficiently handle interconnection of subsystems. Experimental results demonstrate that the proposed method is effective for tasks that were outside the scope of existing methods.
