Wolfgang Pauli Lectures on Physics, Volume 3 “Thermodynamics and the Kinetic Theory of Gases”, 2nd chapter dedicated to the 2"? Law: [...] The second law distinguishes heat from the other forms of energy. It indicates a direction in time and makes apparent that heat is a disordered form of energy. (Pauli 1973)

Fig.2 Double thermoelastic pendulum. A single pendulum with exter- nal perturbations is learned, and the coupling between both systems is achieved via the port-metriplectic framework We develop inductive biases for the machine learning of complex physical systems based on the port-Hamiltonian formalism. To satisfy by construction the principles of thermodynamics in the learned physics (conservation of energy, non-negative entropy production), we modify accordingly the port-Hamiltonian formalism so as to achieve a port-metriplectic one. We show that the constructed networks are able to learn the physics of complex systems by parts, thus alleviating the burden associated to the experimental characterization and posterior learning process of this kind of systems. Predictions can be done, however, at the scale of the complete system. Examples are shown on the performance of the proposed technique.
