Feedforward neural networks or unfolded-in-time recurrent neural networks are prime examples of such graphs. However, there exists a wide range of computations that are easier to describe

WitrynaEquilibrium of Neural Networks. The study on the equilibrium of neural networks originates from energy-based models, e.g. Hopﬁeld Network [11, 12]. They view the dynamics or iterative procedures of feedback (recurrent) neural networks as minimizing an energy function, which will converge to a minimum of the energy.
