New deep neural-operator framework for probabilistic models unveiled

Researchers have introduced a novel deep neural-operator framework designed to handle a wide array of probabilistic models. This framework is theoretically grounded with a universal approximation theorem, establishing explicit network-size bounds under global Lipschitz conditions. The approach is applicable to stochastic processes meeting integrability and general tail-probability criteria, demonstrated through its use in European and American option-pricing problems within the forward-backward SDE framework. A numerical example showcased the model's ability to efficiently determine optimal stopping boundaries for American options without requiring retraining for new strike prices. AI
