[HTML][HTML] An overview of variational autoencoders for source separation, finance, and bio-signal applications
A Singh, T Ogunfunmi - Entropy, 2021 - mdpi.com
Autoencoders are a self-supervised learning system where, during training, the output is an
approximation of the input. Typically, autoencoders have three parts: Encoder (which …

Multi-asset spot and option market simulation
We construct realistic spot and equity option market simulators for a single underlying on the
basis of normalizing flows. We address the high-dimensionality of market observed call …

Funvol: A multi-asset implied volatility market simulator using functional principal components and neural sdes
We introduce a new approach for generating sequences of implied volatility (IV) surfaces
across multiple assets that is faithful to historical prices. We do so using a combination of …

A two-step framework for arbitrage-free prediction of the implied volatility surface
In this study, we propose a two-step framework to predict the implied volatility surface (IVS)
in a manner that excludes static arbitrage. First, we select features to represent the surface …
