WitrynaTo overcome this difficulty, we propose a graph learning framework, called Implicit Graph Neural Networks (IGNN), where predictions are based on the solution of a fixed-point equilibrium equation involving implicitly defined "state" vectors. We use the Perron-Frobenius theory to derive sufficient conditions that ensure well-posedness of the ...

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.
