Deep Neural Networks and Julia

Recently, I have spent some time on simple neural networks. The idea is to employ them as universal function approximators for some problems appearing in quantitative finance. There are some great papers on it such as the one from Liu et al. (2019) or Horvath et al. (2019) Deep Learning Volatility or Rosenbaum & Zhang (2021). Incidentally, I met Liu back when I was finishing my PhD in TU Delft around 2020.
