Contexto: "Despite the success of scientific machine learning for learning the solution trajectories of ordinary differential equations, developing a DL-based framework for learning and simulating the solution trajectories of nonlinear differential-algebraic equations remains an open problem. This is because DAEs present a form of infinite stiffness that may produce gradient pathologies and ill-conditioned optimization problems, leading to the failure of the stochastic gradient descent-based training."

Termo equivalente: estocástico
Definição: "The word stochastic is jargon for random. A stochastic process is a system which evolves in time
while undergoing chance fluctuations."
