Efficient Numerical Wave Propagation Enhanced By An End-to-End Deep Learning Model

no code implementations4 Feb 2024 Luis Kaiser, Richard Tsai, Christian Klingenberg

Recent advances in wave modeling use sufficiently accurate fine solver outputs to train a neural network that enhances the accuracy of a fast but inaccurate coarse solver.

Computing Black Scholes with Uncertain Volatility-A Machine Learning Approach

no code implementations15 Feb 2022 Kathrin Hellmuth, Christian Klingenberg

In financial mathematics, it is a typical approach to approximate financial markets operating in discrete time by continuous-time models such as the Black Scholes model.
