%description
This framework enables forecasting and extrapolating measures of
conditional risk (e.g. of extreme or unprecedented events), including
quantiles and exceedance probabilities, using extreme value statistics and
flexible neural network architectures. It allows for capturing complex
multivariate dependencies, including dependencies between observations,
such as sequential dependence (time-series). The methodology was
introduced in Pasche and Engelke (2024) <doi:10.1214/24-AOAS1907> (also
available in preprint: Pasche and Engelke (2022)
<doi:10.48550/arXiv.2208.07590>).
