Researchers have introduced Operator Neural Jump Ordinary Differential Equations (NJ-ODEs) to address the challenge of predicting continuous-time stochastic processes in infinite-dimensional function spaces. This new framework extends previous NJ-ODE models, which were limited to finite-dimensional processes, by leveraging ideas from Neural Operator methods. The Operator NJ-ODE framework allows for direct handling of function-valued problems, such as predicting yield curves or volatility surfaces, without the need for discretization and its associated information loss. The paper also presents a novel approximation strategy to prove the convergence of these NJ-ODEs to the optimal prediction process, which generalizes prior work in finite-dimensional settings. AI
