Learning parameter dependence for Fourier-based option pricing with tensor networks

no code implementations17 Apr 2024 Rihito Sakurai, Haruto Takahashi, Koichi Miyamoto

In this study, we propose a pricing method, where, by a tensor learning algorithm, we build tensor trains that approximate functions appearing in FT-based option pricing with their parameter dependence and efficiently calculate the option price for the varying input parameters.

Time series generation for option pricing on quantum computers using tensor network

no code implementations27 Feb 2024 Nozomu Kobayashi, Yoshiyuki Suimon, Koichi Miyamoto

To validate our approach, taking the Heston model as a target, we conduct numerical experiments to generate time series in the model.
