Why Is Not Your Neural Network Learning? Insights and Solutions

9 minute read

Published:

I recently stumbled upon a perplexing issue where my neural network, tasked with a regression problem, stubbornly learned to predict the average value of the dataset. After hours of meticulous investigation, I managed to close this issue.

In this blog, I’ll delve into the crux of the problem and share some insights I obtained for training neural networks till now.

Evolutionary Neural Networks for Option Pricing: Multi-Assets Option and Exotic Option

Published in Proceedings of the AAAI Symposium Series, 2023

This paper proposed a novel approach called Evolutionary Neural Network to solve option pricing problems. Evolutionary Neural Network has time-variable parameters, transforming the time-dependent PDEs into ODEs and then applying a standard ODE solver to solve it. This framework is flexible with boundary conditions and can scale up to higher dimensions, allowing pricing customized options.
