Solving Kolmogorov PDEs without the curse of dimensionality via deep learning and asymptotic expansion with Malliavin calculus (Forthcoming in “Partial Differential Equations and Applications”)(Revised version of CARF-F-547)
This paper proposes a new spatial approximation method without the curse of dimensionality
for solving high-dimensional partial differential equations (PDEs) by using an asymptotic expansion method with a deep learning-based algorithm. In particular, the mathematical justification
on the spatial approximation is provided. Numerical examples for high-dimensional Kolmogorov
PDEs show effectiveness of our method.
