Convergence of Neural Network Policies for Risk--Reward Optimization

Chang Chen, Duy-Minh Dang

We develop a neural-network framework for multi-period risk--reward stochastic control problems with constrained two-step feedback policies that may be discontinuous in the state.…

Numerical analysis of American option pricing in a two-asset jump-diffusion model

Hao Zhou, Duy-Minh Dang

This paper addresses an important gap in rigorous numerical treatments for pricing American options under correlated two-asset jump-diffusion models using the viscosity solution fr…

A monotone piecewise constant control integration approach for the two-factor uncertain volatility model

Duy-Minh Dang, Hao Zhou

Option contracts on two underlying assets within uncertain volatility models have their worst-case and best-case prices determined by a two-dimensional (2D) Hamilton-Jacobi-Bellman…

A semi-Lagrangian -monotone Fourier method for continuous withdrawal GMWBs under jump-diffusion with stochastic interest rate

Yaowen Lu, Duy-Minh Dang

We develop an efficient pricing approach for guaranteed minimum withdrawal benefits (GMWBs) with continuous withdrawals under a realistic modeling setting with jump-diffusions and…

A monotone numerical integration method for mean-variance portfolio optimization under jump-diffusion models

Hanwen Zhang, Duy-Minh Dang

We develop a efficient, easy-to-implement, and strictly monotone numerical integration method for Mean-Variance (MV) portfolio optimization in realistic contexts, which involve jum…

Fourier Neural Network Approximation of Transition Densities in Finance

Rong Du, Duy-Minh Dang

This paper introduces FourNet, a novel single-layer feed-forward neural network (FFNN) method designed to approximate transition densities for which closed-form expressions of thei…
