[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 …

A two-step framework for arbitrage-free prediction of the implied volatility surface

W Zhang, L Li, G Zhang - Quantitative Finance, 2023 - Taylor & Francis
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 …
