Fast Option Pricing Using Deep Learning Methods

Abstract: 

In finance, pricing options involves computationally intensive numerical methods like PDE solvers and Monte Carlo simulations. These numerical methods are used to compute the option prices as well as the greeks which are the derivatives of the option prices with regards to inputs like stock price (delta), volatility (vega) etc.

In this talk, we will look at how deep learning techniques can be used for building fast option pricers. A large set of representative training data is generated by using the numerical pricers. Then deep neural networks are used to learn the non-linear pricing functions.

Back propagation can be used to not only train the network (by updating the weights using gradient descent) but also to compute the greeks using autograd.

We will also look at nice interactive tools which will help us better understand how the models work out-of-sample.

Background Knowledge:

Basic knowledge of financial derivatives especially options.
