XNet-Enhanced Deep BSDE Method and Numerical Analysis
Xiaotao Zheng, Xingye Yue, Zhihong Xia +1
Semilinear parabolic partial differential equations (PDEs) are fundamental to modeling complex dynamical systems across scientific domains. The Deep Backward Stochastic Differentia…
Responsive Distribution of G-normal Random Variables
Ziting Pei, Shige Peng, Xingye Yue +1
A -normal random variable does not admit a unique probability law due to volatility uncertainty. For a given test function…
Option pricing model under the G-expectation framework
Ziting Pei, Xingye Yue, Xiaotao Zheng
G-expectation, as a sublinear expectation, provides a powerful framework for modeling uncertainty in financial markets. Motivated by the need for robust valuation under model uncer…
Enhancing Neural Function Approximation: The XNet Outperforming KAN
Xin Li, Xiaotao Zheng, Zhihong Xia
XNet is a single-layer neural network architecture that leverages Cauchy integral-based activation functions for high-order function approximation. Through theoretical analysis, we…
