Nonlinear filtering based on density approximation and deep BSDE prediction
Kasper Bågmark, Adam Andersson, Stig Larsson
A novel approximate Bayesian filter based on backward stochastic differential equations is introduced. It uses a nonlinear Feynman--Kac representation of the filtering problem and…

The deep multi-FBSDE method: a robust deep learning method for coupled FBSDEs
Kristoffer Andersson, Adam Andersson, Cornelis W. Oosterlee
We introduce the deep multi-FBSDE method for robust approximation of coupled forward-backward stochastic differential equations (FBSDEs), focusing on cases where the deep BSDE meth…
