Solving Black-Scholes PDE for Option Pricing: A Unified LS-SVR-Based Hybrid Approach
Researchers compared data-driven and physics-informed machine learning methods for option pricing using the Black-Scholes partial differential equation. They introduced a hybrid model combining Least Squares Support Vector Regression (LS-SVR) and Feedforward Neural Networks. The hybrid consistently surpassed traditional models in both accuracy and speed, crucial for financial use. The study included mathematical proofs, such as the positive semi-definiteness of the Radial Basis Function (RBF) kernel, but noted a need for more real-market data validation.
What it examines
This paper compares data-driven and physics-informed machine learning methods for solving the Black-Scholes equation used in option pricing. It evaluates Least Squares Support Vector Regression, Feedforward Neural Networks, and a new hybrid model, aiming to improve accuracy and efficiency in pricing both European and American options.
What it concludes
The hybrid model outperforms other methods in accuracy and speed, making it valuable for financial institutions needing fast and reliable option pricing. This approach can be applied to other financial models, though further research is needed to address more complex derivatives and real-world market conditions.
