Detralytics invites you to their event

Lunch & Learn | Option pricing in the Heston model with Physics inspired neural networks

About this event

We invite you to participate in our next Lunch & Learn* on "Option pricing in the Heston model with Physics inspired neural networks". It's FREE and OPEN to everyone.

Given in English by our Scientific Director, Donatien Hainaut, and our Actuarial Consultant, Alex Casas, this online session will take place on April 23, 2024, from 12:30 to 13:30.

Accreditation : 1 CPD | 6 PPC

*Our Lunch & Learn sessions discuss our publications over lunchtime, based on the brown-bag session concept.


This Lunch & Learn will present the content of our Detra Note about the same topic.

In absence of a closed form expression such as in the Heston model, the option pricing is computationally intensive when calibrating a model to market quotes. This article proposes an alternative to standard pricing methods based on physics-inspired neural networks (PINNs). A PINN integrates principles from physics into its learning process to enhance its efficiency in solving complex problems. In this article, the driving principle is the Feynman-Kac (FK) equation, which is a partial differential equation (PDE) governing the derivative price in the Heston model. We focus on the valuation of European options and show that PINNs constitute an efficient alternative for pricing options with various specifications and parameters without the need for retraining.
